A spectrum is caused by white light being bent and split (such as through water droplets) into waves of different lengths, each color being visible at a different wavelength range, from widest (red) to narrowest (purple). This effect is called refraction.

    Thank you, Kristen! I'm glad that you enjoyed it. It was for a contest on Associated Content, and I thought to bring the science of light into it so others could learn something from it, too.
