How can white light split into different colors?

If the angle of refraction is spread between 40° and 42° the light will disperse as it's constituent spectrum (from violet to red, respectively, with the other colors falling inbetween). read more

Don't imagine light as just light with a white color, it's more like every other color of the rainbow combined together. A prism can separate white light into the colors of the rainbow that it consists of. read more

Different frequencies of light bend at slightly different angles. Long wavelengths like red bend the least. Blue wavelengths bend the most. Any piece of glass will do this, even a flat one, but in a flat piece of glass the sides are parallel. read more

Visible light, also known as white light, consists of a collection of component colors. These colors are often observed as light passes through a triangular prism. Upon passage through the prism, the white light is separated into its component colors - red, orange, yellow, green, blue and violet. read more
