Scattering occurs when the atoms of a transparent material are not smoothly distributed over distances greater than the length of a light wave, but are bunched up into lumps of molecules or particles. The sky is bright because molecules and particles in the air scatter sunlight. Light with higher frequencies and shorter wavelengths is scattered more than light with lower frequencies and longer wavelengths. The atmosphere scatters violet light the most, but human eyes do not see this color, or frequency, well. The eye responds well to blue, though, which is the next most scattered color. Sunsets look red because when the Sun is at the horizon, sunlight has to travel through a longer distance of atmosphere to reach the eye. The thick layer of air, dust and haze scatters away much of the blue. The spectrum of light scattered from small impurities within materials carries important information about the impurities. Scientists measure light scattered by the atmospheres of other planets in the solar system to learn about the chemical composition of the atmospheres.

Reflection is the change in direction of a wave front at an interface between two dissimilar media so that the wave front returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.\n\nSpecular reflection\nA mirror provides the most common model for specular light reflection and consists of a glass sheet in front of a metallic coating where the reflection actually occurs. It is also possible for reflection to occur from the surface of transparent media, such as water or glass.\n\nDiffuse reflection\nWhen light strikes a rough or granular surface, it bounces off in all directions due to the microscopic irregularities of the interface. Thus, an image is not formed. This is called diffuse reflection\n\nRetroreflector\nSome surfaces exhibit retroreflection. The structure of these surfaces is such that light is returned in the direction from which it came. A simple retroreflector can be made by placing three ordinary mirrors mutually perpendicular to one another (a corner reflector). The image produced is the inverse of one produced by a single mirror.\n\nComplex conjugate reflection\nLight bounces exactly back in the direction from which it came due to a nonlinear optical process. In this type of reflection, not only the direction of the light is reversed, but the actual wavefronts are reversed as well. A conjugate reflector can be used to remove aberrations from a beam by reflecting it and then passing the reflection through the aberrating optics a second time.\n\n\nNeutron reflection\nMaterials that reflect neutrons, for example beryllium, are used in nuclear reactors and nuclear weapons.\n\n\nSound reflection\nWhen a longitudinal sound wave strikes a flat surface, sound is reflected in a coherent manner provided that the dimension of the reflective surface is large compared to the wavelength of the sound. In the theory of exterior noise mitigation, this phenomenon mildly detracts from the concept of a noise barrier by reflecting some of the sound into the opposite direction.

Rayleight Scattering.\n\nThe blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere. This scattering, called Rayleigh scattering, is more effective at short wavelengths (the blue end of the visible spectrum). Therefore the light scattered down to the earth at a large angle with respect to the direction of the sun's light is predominantly in the blue end of the spectrum.

Microphotonics is a branch of technology that deals with directing light on a microscopic scale. It is used in optical networking.\n\nSee link below

You are right! Atomic structure has everything to do with what wavelengths are absorbed, and which ones are reflected. I works with light, and it works with radio waves... Thats how they make stealth aircraft. Funny thing about copper... when powdered and burned, it makes a pretty green color!

the atmosphere contains lots of air molecules which scatter the light that passes through them.\naccording to rayleigh, if the size of scattering particle is very very less than the wavelength of light (eg. air molecule), then light of shorter wavelength will be  scattered more than light of longer wavelength.Since in the visible spectrum, blue has shorter wavelength than red....... it gets scattered more than any other color.

Music is organized sound, so I think the answer would be "irregular vibration patterns".  These links should help.

I think you mean diffraction of light.\n\nIf so then you need to consider light as an electromagnetic  wave form, not as a form of particles - small energy packets called photons. The light, you see, has duel nature - it acts in certain situations as a wave whereas in other situations it is observed to behaves as if it is made of tiny particles.\n\nNow in its electromagnetic wave form light behave very much like water waves. The water waves, for example, when emerge from a narrow openings spread out in form of arcs or semicircles into a wider region.\n\nLight too has this property. It tends to bend round sharp edges and spread into regions where it is not supposed to be. On the other hand if light were composed of particles a burst of particles would always follow a straight line trajectory.

This means in simple words the ability of a substance to absorb electromagnetic radiations. Named as "epsilon". It is measure of how easily the radiation, while passing through the substance, becomes "extinct". Oftenly it is called molar extinction co-eff.\n\nThe more the absorption of em radiation the higher the extinction co-eff and vice versa.

Yes...\n\nThe refraction indecces\n\nn =c/v, but c = wave lenght * frequency

there are basically 2 parallel mediums of propagation. air and the outer liquid hemisphere. i expect to see interference also as there will be addition of waveforms.

In my opionion, It is more like a very tightly compacted wave, of which light is a part. When matter is released back to it original wave state it emites, heat wave, sound wave, and a full spectrum of radiation waves from micro, to light, to gamma and everything that surrounds that visible and invisible spectrum.

it ain't pretty but here goes nothing.\n\n\n\nsunlight is all hues\nN and O scatter the light\nblue is spread the most\n\n\n\n\nThe first thing to recognize is that the sun is an extremely bright source of light -- much brighter than the moon. The second thing to recognize is that the atoms of nitrogen and oxygen in the atmosphere have an effect on the sunlight that passes through them. \n\nThere is a physical phenomenon called Rayleigh scattering that causes light to scatter when it passes through particles that have a diameter one-tenth that of the wavelength (color) of the light. Sunlight is made up of all different colors of light, but because of the elements in the atmosphere the color blue is scattered much more efficiently than the other colors. \n\nSo when you look at the sky on a clear day, you can see the sun as a bright disk. The blueness you see everywhere else is all of the atoms in the atmosphere scattering blue light toward you. (Because red light, yellow light, green light and the other colors aren't scattered nearly as well, you see the sky as blue.)

If we assume that the X-ray scattering of the 'unmodified' type observed by Prof. Compton corresponds to the normal or average state of the atoms and molecules, while the 'modified' scattering of altered wave-length corresponds to their fluctuations from that state, it would follow that we should expect also in the case of ordinary light two types of scattering, one determined by the normal optical properties of the atoms or molecules, and another representing the effect of their fluctuations from their normal state. It accordingly becomes necessary to test whether this is actually the case. The experiments we have made have confirmed this anticipation, and shown that in every case in which light is scattered by the molecules in dust-free liquids or gases, the diffuse radiation of the ordinary kind, having the same wave-length as the incident beam, is accompanied by a modified scattered radiation of degraded frequency. \nThe new type of light scattering discovered by us naturally requires very powerful illumination for its observation. In our experiments, a beam of sunlight was converged successively by a telescope objective of 18 cm. aperture and 230 cm. focal length, and by a second lens was placed the scattering material, which is either a liquid (carefully purified by repeated distillation in vacuo) or its dust-free vapour. To detect the presence of a modified scattered radiation, the method of complementary light-filters was used. A blue-violet filter, when coupled with a yellow-green filter and placed in the incident light, completely extinguished the track of the light through the liquid or vapour. The reappearance of the track when the yellow filter is transferred to a place between it and the observer's eye is proof of the existence of a modified scattered radiation. Spectroscopic confirmation is also available. \n\nSome sixty different common liquids have been examined in this way, and every one of them showed the effect in greater or less degree. That the effect is a true scattering, and secondly by its polarisation, which is in many cases quire strong and comparable with the polarisation of the ordinary scattering. The investigation is naturally much more difficult in the case of gases and vapours, owing to the excessive feebleness of the effect. Nevertheless, when the vapour is of sufficient density, for example with ether or amylene, the modified scattering is readily demonstrable.

This phenomenon is call total internal reflection.\nThe theory explaining the phenomenon is detailed in most good physics optics textbooks.

there is an optical effect like this ( it is just a refraction at an interface - like water and air ) and sorry i can't remember either ( i will search tho )\n\ncool i searched the term ATMOSPHERIC REFRACTION and guess what LOL( go to Wikipedia )
