Refraction and Reflection

Light Energy

Light Energy -radiant energy that our eyes can't see from the visible part of the electromagnetic spectrum.Light energy is electromagnetic radiation. This means it is a combination of electrical and magnetic energy. Light energy is given off by electrons in an object. Light moves in waves. All light energy is in a spectrum that include waves with different frequent and Wave length.


Absorption of light occurs when an object does not reflect or transmit the light. Black objects absorb all light and white objects absorb no light.
