Light is visible electromagnetic waves that allow humans to see. Light interacts with different materials in various ways through reflection, refraction, absorption and transmission. Optics is the branch of science that studies how light interacts with objects, such as how plants appear green because leaves absorb all light wavelengths except green.

How Light Interacts With Different Materials
The light that is visible to the human eye is called visible light. It is the small part of the
electromagnetic spectrum which affects our vision. Light is propagated in space as
electromagnetic waves. This is known as electromagnetic wave theory of light. The primary source
of visible light is the sun. The visible light allows us to see the color that is not absorbed by the
objects. For example, you see most plants as green because the leaves absorb all colors of the
visible light except for green. To understand light further, you have to learn how it interacts with
different objects. This branch of Science is called optics. Optics is the study of refraction, reflection,
absorption, and transmission of light.
