Why is light called an electromagnetic wave and why it is called by this name?
I see. So, how do these waves interact with matter and produce the visual effects that we see?
When light waves encounter matter, they can reflect, refract, or absorb. Reflection occurs when the waves bounce back from the surface of an object. Refraction happens when the light waves change direction as they pass through a substance of different density. Absorption happens when the waves are absorbed by the matter and converted into other forms of energy, like heat. These interactions produce the visual effects we see.
