• Refraction is the bending of light when it passes from one medium to another.
• Refraction is the absorption of light in a medium.
• Refraction is the reflection of light off a surface.
• Refraction is the scattering of light in a vacuum.

Why does the visible light spectrum have different colors?

• Different colors are caused by the temperature of the light source.
• The visible light spectrum has different colors due to varying wavelengths of light.
• The visible light spectrum is made up of only three primary colors.
• Colors in the spectrum are determined by the speed of light.
