What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is produced by the vibrations of electrically charged particles.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.
