Light Energy

light

• to allow light to pass through
• When light strikes some materials, almost all of the light goes through it.
• A form of energy that can be seen.
• Substances of different densities through which light energy travels and changes. Like water, glass, plastic, paper, etc...

prism

• When light strikes other materials, only some of the light passes through it.
• Reflects all white light (reflects heat).
• The term for any wave that hits a surface and bounces off.
• An object that separates white light into bands of colored light. (It refracts light.)

refraction

• The term for any wave that hits a surface and bounces off.
• We see red because an object absorbs all colors but red. We see red because it is the only color being reflected back to our eyes.
• The bending of light as it passes from one material to another. When light goes through glass, water, or clear plastic or when light moves from cold air into warm air.
• When light strikes some materials, almost all of the light goes through it.
