Type your answer here... OK. White light is made of the colours of the spectrum (Red, Orange, Yellow, Green, Blue, Indigo and Violet - these are the same as the colours of the rainbow). The reason you see these colours instead of wwhite when you shine white light through a prism is that the prism "bends" the light - which splits it into the colours of the spectrum.
Red light is the longest, so it is bent the least, and Violet is the shortest - so it is bent the most.
This is also how rainbows are made - the rain droplets act as prisms to disperse (split) the light into the colours of the spectrum.
Most light is a mixture of colors of the spectrum.* White light is composed of all colors. The different wavelengths of light are refracted at different angles, which separates them out into the constituent colors of the original light source. *Laser light is monochromatic.
The reflection comes through the prism and different colors are different wavelength of sunlight from violet to red in the order of violet, indigo, blue, green, yellow, orange and red.
The different colors in white light are due to different wavelengths of light being bent at different angles as they pass through the prism. This separation of colors is called dispersion, with shorter wavelengths (like blue and violet) bending more than longer wavelengths (like red and orange), resulting in the spectrum of colors we see.
Incident light hits a prism, refracted or reflected light emerges from it. In what manner it is different from the incident light depends on the angle of incidence and the angles of the prism. Commonly it may be refracted, dispersed or reflected back.
When red light from a laser shines on a prism, it will be refracted (bent) by the prism and split into its component colors (red, orange, yellow, green, blue, indigo, and violet). This is due to each color having a different wavelength and therefore a different angle of refraction when passing through the prism.
A rainbow is made of sunlight that is refracted, or bent, when it enters a raindrop, reflecting off the inside surface of the drop. This creates a spectrum of colors due to the different wavelengths of light being separated as they pass through the raindrop and then emerge as a colorful arc in the sky.

Different colours travel at different velocity in a glass medium. Refractive index is defined as the ratio of the velocity of light in free space to that in medium. So refractive index becomes different for different colours. Now by Snell's law the refractive index is inversely proportional to the angle of refraction. Hence different colours get deviated at different angle of refraction. So the splitting of composite white light into its constituent colours has become possible. If these again fall at a parallel surface as in the case of a glass slab the colours split would get combined back and emerge as white light. But we have prism where the two refracting surfaces are at inclined and further splitting takes place and hence dispersion.
No light will emerge from the different color paper, since all other colors except yellow have already been removed by the first one. The second one appears black.
Whit light doesn't separate unless it passes through some medium. It is separable because it consists of many different light frequencies. Different colors (frequencies) of light have different refractive indices for the same interface. So, when white light is passed through a prism, for instance, different colors deviate (are refracted) to different extents. This is how the different frequencies in white light are separated into what is called the visible spectrum.
If all colors are passed through another prism white light will emerge This may sound funny, but check out the pink Floyd album dark side of the moon, look at the front then look at the back it is an upside down image with colors going in and light going out. Imagine those are the colors from the front. (The triangle is a 2D interpretation of a triangular prism)
