Why does light refract when passing through a prism or raindrop?
What happens to the speed of light waves when moving from air into a denser medium like glass or water? How does wavelength determine the angle?

Light waves slow down when entering a denser medium. Because different wavelengths (colors) slow down at variable rates, they bend at distinct angles.
