what is light?

We all know what light is. We also know that Sun, fire, bulbs, and glowworms all give us light. But what exactly light is ?

Light is a form of energy that which we can see. It is made of billions of tiny particles called photons. these photons travel from one place to another in waves. the light that we can see consists of photons that move at a wavelength that makes visible, and is known as visible light.

Visible light is actually made up of different colors. Among the different photons that are in visible light, the ones that have the longest wavelength look red to us, and the ones that have the shortest wavelength look violet to us.

Red, green, and blue are the primary colors of light. Mixing them in various ways will make all other colors, including white. Isn't that amazing?
