Is the vertical movement of a wave measured from the lowest point to the highest point??
372586
Measuring the height of a wave is typically based on lowest to highest (after all, the wave could start at any point on the wave!)  The technical term for the vertical component of a wave is the amplitude, which is the average of the lowest and highest points of the wave.

Because Debrogelie's wave equation has momentum on the bottom, which is dependent on mass. Therefore, as mass increases, the wavelength decreases. This means that all things that we can see have such a low wavelength that its impossible to see, let alone measure.

The real question is do you measure from the top or bottom

The Pacific and Atlantic Oceans have different heights with the highest sea surface in the Western Pacific. But don't worry about all that Pacific water rushing into the Atlantic and flooding the Texas coast.\n\nAs far as equalizing levels, this has occurred but introduces an idea that many people find hard to imagine. The difference in heights is a result of a "dynamic equilibrium". Dynamic means changing, but equilibrium means balance, which we usually think of as no change. How can this be? Think of an unchanging balance as one like you can find on a scale where you place the same weight on both sides and it will balance -- always and forever. There is no new weight added or removed, no energy added or removed. This is Static equilibrium, an unchanging balance. A dynamic equilibrium involves the balance of changes. Imagine on your scale that you have cups instead of weights. Each cup the same size and is being dripped into and overflows but it will still balance if the fluid dripping in and out balances on both sides. Here there is a dynamic equilibrium with changes in mass or weight. If we want to imagine an equilibrium that also includes energy, let's have one side of the scale have a smaller cup than the other. Water drips in and overflows, but the two sides can never balance because the two cups can never hold the same amount of water. This gets a little complicated, so hang in there. The cups can't balance each other with weight alone. The lighter cup will go up and the heavy cup will go down. You can make a dynamic equilibrium by pushing down on the lighter cup. Now you have two cups with different amounts of water that balance. Hmmm? This can only happen with the addition of energy.\n\nThis is similar to how the sea surface heights can be different -- there is a dynamic equilibrium. It is indeed affected by the rotation of the Earth which is where some of the energy used to maintain the balance comes from. More comes from the Sun and its heat. The energy acts through winds on the sea surface and currents which tend to cause water to "pile up" where currents are swift. Imagine the surface of your morning juice in its cup. If you swirl that juice, the surface is no longer 'level' but slanted (and the slant rotates with the swirl). This slant is maintained as long as you continue to swirl the cup. You have an equilibrium that requires energy. The moment you stop adding energy by swirling, the surface of the juice levels out. It is now a static system with a static equilibrium that is simple to understand.\n\nThere is a huge science project (yes, scientists do science projects too) called TOPEX/Poseidon that looks at the sea surface (and other ocean information) from orbiting satellites. And there are oceanographers who specialize in studying the sea surface and what causes it to be different from flat. Some of this information is available on the Internet including really cool pictures made from satellite information.

High tides get higher and low tides get lower.\n\nIf I'm not mistaken... this is what happens at the times of the equinoxes.... the sun and moon line up... pulling the tides to higher highs and lower lows...

Such a pulse produces a standing wave. In such standing wave energy is not transferred from one place to another.\n\nAt each instant we see a wave, but the waves do not move.\n\nThere are certain points which never move, they are called nodes.\n\nBut between nodes the points are displaced.\n\nAt one instant, all points are motion less.\n\nAfter this instant, points that previously went up will now come down and vice versa.\n\nExcept the nodal points, all points are oscillating between potential and kinetic energy. \n\nThe maximum displacement corresponds to potential energy and the mean position corresponds to kinetic energy.\n\nAt the instant when all points are motion less, ALL POINTS EXCEPT THE NODAL POINTS have kinetic energy, by which they continue their oscillation.

neap tide is the answer.\n\nExplaination. Since it is the effect of the moon and sun's gavity that causes tides, there are high tides closest and farthest away from the two of them. When they are lined up, spring tide occurs, resulting in the highest and lowest possible tides. However, when the sun, moon, and earth are at a 90 degree angle, the difference between high tide and low tide is the least(Because the effects of gravity are spread out). This is neap tide.\n\nPS. At neap tide there is still a visible distinction between the high and low tides. This is because the sun and moon's gravity and distance from Earth are not the same.

Yes..\n\nBut isn't that obvious? Imagine a water drum with a tap at the bottom. By opening the tap the amount of water flowing out increases!\n\nThe pressure of the water at the bottom will be same in both cases (propotional to the height of the water)\n\nThis can be proved by the application of the Bernoulli's Equation between two points -\na. One at the surface\nb. One at the very end that is open to the atmosphere of the tube\n\nBernoulli's equation basically states that the following equation is a constant in the system\nC = Pressure + 0.5*d*V^2 + d*g*H\nwhere,\nd = specific density of the liquid\ng = 9.8 m/s^2\nH = height measured from a reference point (positive upwards)\nV = velocity of the fluid\n\nWe assume that the tank capacity is large enough, so that the velocity of a point at the surface is near zero (even though water is flowing out).\n\nThe pressure is also equal for the two said points (atmospheric pressure)\n\nSo we get,\n0.5*d*v^2 = d*g*h\nwhere,\nv = velocity at point b\nh = veritical height difference between points a and b\n\nSo,\nv = sqrt(2*g*h)\n\nAnd the fluid flux, the rate of water flow in volume per time unit is,\nflux = Area * Velocity\n= A * sqrt(2*g*h)\n\nIn english,\nThe volume of water flowing per second is,\n1. Propotional to the area of the apperture that is exposed to the atmosphere (and not the area of the tube in between)\n2. Propotional to the root of the height difference between the surface and the exposed end of the tube.\n\nAll this assuming ideal liquid, streamlined flow, blah.

Energy is directly proportinal to the square of velocity as you know (Kinetic Energy)\nas far as the velocity of a wave is concerned it wavelength * frequency\nso it has to be either frequency or wavelength,the choice is left to you\nif u asked me i had rather choose to go with frequency

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.

Gravity is an inverse square law for the further you are from the centre of mass the lower the graviational pull you feel. So yes gravity is less on the top of a mountain (and this has been measured) also these would be less air resistance as the air is of a lower density. These two factors would allow you to jump high, assuming you were on oxygen.

The same way it travels through air, in waves.  It just doesn't make it very far.

Let rock be thrown at an angle of θ at a velocity of Vo\n\nThen vertical component = Vo sinθ\nand horizontal component = Vo cosθ\n\nAlso acceleration in horizontal direction = 0 \nand acceleration in vertical direction = -g = -9.8 m/s²\n\nVertical direction\n\na = -9.8\nv = u + at\nSo Vt = Vosinθ - 9.8t\nand s = ut + ½at²\nSo h = Vosinθ*t - 4.9t²\n= 0 when it is at ground level\nie t(Vosinθ - 4.9t) = 0\nSo t = 0 or Vosinθ/4.9 ... ****\nSo it will take Vosinθ/4.9 s to cross the river.\n\nHorizontally\n\nVt = Vocosθ + 0 (as a = 0)\n= Vocosθ\n\ns = ut + ½at²\n= Vocosθ * t\n\nSo 75 = Vocosθ *Vosinθ/4.9\n= Vo².sinθcosθ / 4.9\n= Vo² * 2sinθcosθ / 2*4.9\n= Vo² * sin2θ/9.8 \nThus Vo² * sin2θ = 75*9.8 = 735\nThus Vo² = 735/sin2θ\nNow least value of Vo occurs when Vo² is minimum and this will occur when sin2θ is maximum (=1)\n\nSo Min possible Vo = √735 \n≈ 27.11 m/s (projected at 2θ = 90° ie θ = 45°)\n\nMinimum time = Vo*sin45°/4.9 (from ****)\n≈ 3.91 s

If every point on the line has the same x coordinate, the line would be vertical. The formula for slope is rise/run. The "run" part would be the change in the x coordinates. Since there is no change, "run"=0. Dividing by zero is undefined, so the line's slope is undefined (not zero). Only vertical lines have an undefined slope.\n\nAlso, try plotting points. Choose any x value, and you will see that if every point has that same value, the line will be vertical regardless of the y value.\n\nAlso notice and vertical lines are not functions as they do not pass the vertical line test.

>The lowest point on earth is located on the shore of the Dead Sea, on the Israel-Jordan border. The altitude of this point ranges from 394 meters (1,292 ft.) to 400 meters (1,312 ft.) below sea level. Time is the reason this value has changed. With the low replenishment rate, extreme heat, and high evaporation, the level of the Dead Sea is lowering at a rate of approximately 1 meter every 10 years.\n\nThere will never be an exact measurement for the depth of the shores of the Dead Sea. It will increase, below sea level, constantly, until the water level reaches zero. This situation would make the lowest point on earth the sea's floor bed, which is almost a half mile down, or 800 meters (2600 ft.) below sea level.
