What is light?


Most of us would say light is something that makes things visible or that it’s the glow from the sun. Well, you are correct. But another way to understand light is as a form of energy that behaves like a wave. There are different forms of light, both visible and invisible. Scientists refer to all forms of light energy as electromagnetic radiation.
