Light

• White light is a mixture of all the colors of the rainbow.
• The study of light is called optics.
• Intensity refers to the degree of brightness of light.
• Light travels faster through some materials than others. This causes refraction (bending) of light as it passes from one material to another.
• A prism separates white light into its component colors because different wavelengths bend at slightly different angles.
• Light is just one form of electromagnetic radiation or electromagnetic waves.
• What color of a star is the coolest?
