What is it called when light moves through water?
Nothing special. But when light travels from one medium to another (from air to water for example) it is refracted. One answerer said a rainbow. A rainbow is caused by the different wavelengths (colors) of light are refracted at slightly different angles, so that we see different colors appearing at different positions.
How does an ordinary rainbow occur from a light ray hitting a drop of water?
The molecules in the water refracts visible light like a prism and seperates light into the different wavelengths and thus colors creating the rainbow.
The termrefraction means what in terms rainbows?
Water droplets refract different wavelengths of visible light differently. Blue wavelengths are less "bent" than red wavelengths, so the blue portion of the rainbow is towards the inside edge of the rainbow.
How does refraction cause rainbows?
The actual mechanism is a little difficult to explain without a drawing. But, simply stated it's because white light contains all colors. And, when light goes from one medium into another (in this case from air into water droplets) the light is bent, and each color is bent a different amount, thus separating them. Then the beams of color are bent a second time as they go from the water back into the air. This fans out the colors into the rainbow you see. This bending of light is called refraction. As I said, without a drawing it's difficult to explain why the colors bend different amounts as they pass through the water/air boundry, but it's because different colors are different frequencies or wavelengths of light, and different wavelengths are bent different amounts.
Light traveling through the air moves in a straight line an object viewed through water looks different because the light rays that travel through water are what?
BENT
A range of light waves with different wavelengths?
water
Why do rainbows form in misty water?
When the water droplets are in the air, light from the sun passes through them, and because of their small size and refractive properties, the water droplets break the sunlight into its constituent colors of light at different wavelengths.
Why does the rainbow display colors and how?
Rainbows are caused by the refraction of the sun's rays in the drops of water in the sky. Refraction is the bending of light when it passes through a surface where the index of refraction changes. This occurrence is similar to what happens when light passes through a prism. The index of refraction of the water drops is different for different wavelengths. Thus, the light bends more for violet light than for red light. When the light passes through a prism (or water droplet), the different wavelengths of light are refracted by different amounts, separating the different colors of light. This occurs in a rainbow, where the light passes into the water droplet, reflects off the back of the droplet, and come back out through the front. The angle at which it comes back out the front will depend on the color of the light. The shape of the rainbow is determined by the angle between the sun, the observer, and the water drops.
Why can you see though water and glass?
You can see through them because light goes through them, and our eyes are built to see certain wavelengths of light.
Splitting of white light is due to?
Light has a constant speed in a vacuum, however when it passes through a different medium (such as air, water etc) it is slowed down as a result of its interaction with matter. If the light enters a different medium on an angle then it bends. The degree to which light is slowed down depends on the wavelength of the light. White light is made of light from lots of different wavelengths (eg blue light, red light, green light). The different wavelengths (different colours) are slowed down different amounts so bend more/less causing the light to spread out.

Does osmosis cause food coloring to change the color of water?
It absorbs different wavelengths of visible light
Why are plants under the sea a different color than land plants?
The water refracts the light so aquatic plants receive different wavelengths of light than their terrestrial counterparts. Accordingly, the plants have different pigments to trap the different wavelengths which accounts for the difference in color.
Is the speed of light is the same in every medium?
No; a denser medium will slow the light down. When the speed of light is quoted, unless otherwise stated, it is implied that it's through a vacuum. The primary example of this is the speed light travels through water or glass. The different speeds are what create the rainbow effect, essentially splitting the light by slowing down different wavelengths at a different rate.
What happens when light passes through something?
The velocity of light is greatest when travelling through a vacuum. When travelling through something else, a glass material say, then its velocity is slower. The refractive index is the ratio of the speed of light in a vacuum to the speed of light in that substance. For example light travels in a vacuum about 1.3 times as fast as in water, so we say water has a refractive index of 1.3. And it is likely that the velocity in the glass will be different at different wavelengths of light.
