How are waves formed?

Waves are formed in three ways, gravity, wind and earthquakes. Gravity is responsible for the high and low tides. High tide is when the water is the deepest and low tide is when the water is most shallow. The rise and fall of the water level causes waves to form.\n\nThe second cause of waves is wind. The wind can be light and only cause small waves. These waves can be as tiny as ripples in the water. Young children can practice making waves by blowing on a bowl full of water.\n\nWind can also cause very large waves that make being in the water very dangerous. Even large ships don't want to be caught in a storm with huge waves.\n\nThe type of wave wind causes depends on how hard the wind is blowing, how long the wind blows and how much ocean the wind blows over.\n\nLastly, waves can be caused by earthquakes. Earthquakes are the result of two of the earth's plates rubbing together. Just as we stumble or fall during an earthquake, water also reacts to the power force. The earthquake pushes the water away from the epicenter of the quake and can cause some pretty large waves.

If you are asking how rocks are formed, there are three main processes: 1) Igneous rocks are formed by the solidification molten magma from deep in the earth; 2) Sedimentary rocks are formed by pressure acting on sand or other small fragments under a body of water or under other rock layers; 3) Metamorphic rocks start as another type, but are changed into a different, often more complex structure or crystalline matrix by the action of pressure, heat, friction, and/or water.

How droplets form:\n\nRain droplets are formed from water vapor in the atmosphere that condenses onto dust particles.  Water vapor is lighter than air, but water is not.  The condensation onto the impurities in dust (nucleation) is more kinetically favorable than a sudden, rapid condensation of all the water in the air (making a splash).  This nucleation phenomena is very similar to observations you can make when you boil water (or let carbonated beverages bubble).  The bubbles will form (nucleate and grow) at tiny cracks and imperfections.  (A very smooth container will have fewer bubbles). Eventually the bubbles get big enough (buoyancy overcomes surface tension) and they rise to the surface.  The main differences between this and rain is that these gas "droplets" fall upward because of buoyancy and they have to overcome an adhesive force to start falling, whereas rain just has to fall fast enough to escape air currents.\n\nThere is another less kinetically favorable mechanism for boiling water that you can sometimes repeat in a microwave, but it is very dangerous.  If you heat water in a microwave, it is possible to get it higher than the boiling point because there hasn't been sufficient time for steam bubbles to form and grow and rise to the surface.  As soon as you touch the surface of the superheated water with say a spoon you could be providing a nucleation site and the water will suddenly boil very dangerously.  If you do this experiment, be very careful.\n\nIf rain WERE observed to fall as a sudden splash rather than as droplets, an analagous condition would be that all of the carbonation in your soda will come out in a sudden blast of carbon dioxide, making a mess and giving you flat pop instantly.  Both processes involve nucleation and growth of droplets (bubbles).\n\nHow droplets fall to the earth:\n\nAll objects heavier than the air will fall to the earth, accelerating until they reach their terminal velocity (the fastest they can go relative to the air speed because of drag).  Really small objects, like rain droplets or insects have very small terminal velocities, so they can get buffeted around without falling much.  Once a rain droplet gets big enough, it can finally fall to the ground at a reasonable speed.  It has a limit on how large it can get because the bigger it gets the faster it falls.  Some basics behind the math follow.\n\nThe terminal velocity is reached when the aerodynamic drag force exactly balances the gravitational force.  The aerodynamic drag force increases with surface area and with velocity (lets consider it to be proportional to the velocity in this example...this is true for sufficiently small objects).  The gravitational force increases with mass (or at constant density) volume.  Volume is roughly proportional to the cube of the relavant length scale of the object.  Surface area is roughly proportional to the square of the length scale of the object.\n\nThus the ratio of the drag force to the gravitional force is c*v*L^2/L^3 = c*v/L, v is the falling velocity, L is typical length scale of the object (like a meter for a person, a foot for a bowling ball, a cm for a big bug), and c is a parameter that lumps together the effects of shape, viscosity, density, and so on.\n\nSo when this ratio c*v/L = 1, the velocity must be the terminal velocity, the fastest the object can fall, v_t.  If you rearrange the equation you see that c*v_t = L.  This means that for a given object with the same physical properties and shape but differing size, the bigger object will fall faster.

waves don't always come to shore, they go in most every direction, the reason you see them close to shore is the sloping land under the water makes it apper to get bigger and more pronouced, as it nears the shore. thus making it seem like they always come to the shore.

The winds cause waves on the surface of the ocean (and on lakes). The wind transfers some of its energy to the water, through friction between the air molecules and the water molecules. Stronger winds (like storm surges) cause larger waves. You can make your own miniature waves by blowing across the surface of a pan of water. \nWaves of water do not move horizontally, they only move up and down (a wave does not represent a flow of water). You can see a demonstration of this by watching a floating buoy bob up and down with a wave; it does not, however, move horizontally with the wave. \n\nTsunamis (sometimes called tidal waves) are different from surface waves; they are usually caused by underwater earthquakes, volcanic eruptions, or landslides.\n\n\nI hope this helps....\n\nDon

All light waves dissipate through space in a wave function pattern.  When they interact with obstacles, these wave patterns can cause interference patterns like waves of water.

It looks like diffusion. \nSound waves are reflected between parallel lines so that the mulitple reflections makes sound waves diffuse from one point to other. This is the best logical explaination i can think of. But additional info on this question can help to explain further.

The more wind the higher the waves.\n\nWhen wind blows over the ocean's surface, it creates waves. Their size depends on how far, how fast and how long the wind blows. A brief, gently breeze forms patches of tiny ripples on the surface called catspaws; strong, steady winds over long distances create large waves. But even when you feel no wind at all, you may encounter large swells created by distant storms.

The most difficult part of understanding things that happen at the microscopic and nanoscopic scale is that a lot of the rules that apply in our everyday lives simply don't work with elementary particles.  If you try to visualize these things, you'll probably end up with some wrong conclusions.\n\nThat said, light waves are fundamentally different from any other wave, such as water, sound, etc., because they do not travel through a medium.  A sound wave travels through air molecules, a water wave travels through water, but a light wave doesn't travel through anything.  To make matters even more confusing, light also has particle-like properties, yet it has no mass and no molecular weight.  A light particle, or photon, is considered an elementary particle, like an electron, proton, or neutron, so it has no molecular make-up, either.\n\nWaves that travel through a medium also do not have a molecular make-up.  Think of a Slinky, for instance.  If you shake one end of the Slinky, a wave travels through the Slinky to the other end, but there's no molecule form for that wave.  The wave basically just energy traveling down a line.  One molecule pushes another molecule pushes another molecule and so on and so on.

The wavelength is shorter but the speed is the same, so the oscillations in the field are at a higher frequency, and that means it takes more energy to create them and they provide more energy when they are absorbed. Something like that.

HOW A RAINBOW FORMS:\nWhen light travels from one medium to another, it bends. In other words, it changes direction and moves at different speeds in different mediums. This property of light is called “refraction”. \nWe also know that white light is made up of different colours. Different colors of light have different frequencies. Except in vacuum and air, they travel at different speeds in different mediums.\nIf you were to allow a beam of light to pass through a simple prism, it will bend when it enters the prism, when it leaves the prism it bends again. The different colours of the white light travel with different speeds inside the prism. The slanted surfaces of the prism makes the different colours emerge separately, thus in addition to bending light as a whole, a prism separates white light into its component colors. This splitting of light into its component colours is called dispersion, where prism is a dispersing element.\nThis is exactly what happens when the sun rays hit droplets of water. When the sunlight strikes a raindrop, the light is refracted (bent) because the light is moving from one medium(air) to another( water). Drops of rainwater can disperse light in the same way as a prism.. When the light comes out of the water droplet, the sun's rays (white light)have now been split into their component wavelengths (colors). In this way, each individual raindrop behaves just like a prism, dispersing white sunlight into its seven component colors and a rainbow is formed. \nThe rainbow we see is thus a result of many, many raindrops bending the sun's rays.\n\nWHY U SEE 5 COLORS:\nDont worry much! there are many colors in rainbow but we see only those who are flowing in a great band. i mean which have more thickness! some colors dont have much thickness there, so it becomes tough to see them. we generally see 5 colors where it is said that rainbow have 7 colors. sometimes we see only 3! it depends on rainbow too, and changes from rainbow to another! depends on the sun and the intensity of rain too.\n\nBut to take precautions u can go and see a doctor!

There was only pure energy of which some formed into tiny bundles that fly in waves. We named those bundles of energy "photons". We named the size of waves that they fly in the "electromagnetic spectrum".  Photons can come together and form tiny shimmerings that we call "particles".  We also call those particles, "matter". Those particles can come together and form families that we named "atoms".  Atoms can come together as elements. Elements can come together and form compounds.  Compounds can come together and form organic compounds. Organic compounds can come together into lifeforms capable of consciousness and possessing senses. All "matter", including you, is made of a symphony of tiny shimmerings of photons, or pure energy.  Here is a real picture that we have recently made of the beginning of the Universe when all that energy appeared:\nhttp://www.princeton.edu/pr/pwb/03/0217/

A sine wave is a basic waveform which originated when men wanted to name the shape that came when they had a long rope and made it move up & down.. Now.. sine wave is an important wave in electric circuits.. The electricity tat is generated is a sine wave & i needn't list wer u use electricity..it is a representation for a sound wave, an oscillation, sometimes a light ray, etc..etc;

water is always flowing. there are currents within a stand-alone puddle. waves constantly crash onto a beach, proving there is no specific point in which they stop. They can go further under the right circumstances. The only reason they don't is due to angular force of gravity. gravity pulls all matter toward the core, including water. should land reach higher above the water's level, the water shall not overtake the land, unless as specified above. since land is solid, or several solid objects, and water is a fluid, land shall not dissolve quickly to a flat line as water does.

winds and air tunnels cause the waves.... and more accurately .. its the high and low pressure that coz the winds to move....:)
