The world around you is full of wonderful colors. The beautiful flowers, the green meadows and the blue sky show different colors. We see colors only when light is shining. When it is dark we cannot see colors. Sunlight is made up of a number of colors but what you see is really white color. When all the Sun’s colors are mixed together, the resulting color is white. Different colors of the light travel at different speeds in glass and in water. When the white light of the sun passes from air to water or air to glass, the different colors of the sunlight bend at different angles thus separating into the individual colors we see. Scientists generally use a glass triangle called a prism to experiment with light, when the white light hits the glass prism, each color of the light bends at a different angle and the different colors separate into a rainbow.
