Diamond, because its facets have more surfaces from which to bounce light than does a pane of glass.
The thickness of the glass causes the white lights' components to bend and spread out its colors. The thicker the glass the more it bends. The red would be at the thickest and blue at the thinner part. Light actually slows down.When light passes from one medium to another it is refracted, that is bent, the amount of bending depends on the wavelength. Different colours have different wavelengths and as white light is made up of all colours each is bent by a different amount, so the light is split
Light bends towards the normal when it touches glass or water because the light travels from optically rarer medium to optically denser medium. Here, air is optically rarer medium and water or glass is optically denser medium. Light slows down in the denser medium. As one end of the wave front hits the interface before the other, we get a turning effect, just as when people march in a line abreast the line will bend if the people at one end slow down.
The pencil appears bent because of "refraction". Simply put, light can't travel as fast in water as it does in the air. The difference in speed causes the image to appear to bend a bit. See the related link for more details.
When light is directed at transparent materials, it bounces off of the particles and is refracted accordingly. This causes the light to bend according to the materials refraction index. The higher the refraction index of the material, and the thicker it is, the more it bends the light and separates the colors.
It is because the glass has more refractive index than air which makes the light bend more through glass than air.
It will bend more.

Eyeglasses refract light to correct for problems with the eyes. As the light needs to be bent more, the glass needs to be thicker to make the light bend farther.
more the incoming light will be refracted (bend) in the material.

this is called a tropism, where the growth of a plant in a particular stimulus, (light in this case). A chemical called auxin causes the elongation of cells. When a shoot is illuminated from one side, auxin is transported down the shaded side. This shaded side then elongates more rapidly than the illuminated side, causing the shoot to bend towards the light. Also the stimulus(light) must be detected by the tip of the plant shoot or root.

The blue light is refracted more.
Light travels in a straight line, as long as it is propagating through a constant medium. In space, space is pretty much empty, so the light travels in a straight line. When light passes into a different medium, such as from space into air or from air into glass, the light is bent or "refracted". You can see this for yourself; poke a straight stick into a pond or pool of water. Look at the stick. The light reflected from the stick to your eye allows you to see the stick, but the light from the part of the stick that's in the water is bent - so it appears as if the stick itself is bent. The light from the stick through the water is refracted differently than the light from the stick through the air. The greater the density of the material, the more the light will be refracted. To magnify light, we need to gather in a lot of light and bend it into a smaller area. We can use curved glass surfaces (or curved mirrors) to bend the light into a smaller area, which magnifies the light. The more dense the glass is, the more the light will be bent into a smaller area.
1) The amount of light refracted is dependent on the angle and wavelength of the light entering a medium, as well as the change in densities of the mediums. 2) A glass prism causes a type of refraction called dispersion where the individual colors of the white light are separated making a rainbow. 3) Shorter wavelengths of light bend more than longer wavelengths. 4) The refraction is caused by a change in velocity of the light waves. 5) The light waves frequencies remain constant during refraction.
