What is light?
We all know what light is We also known that the sun, fire, bulbs, and glowworms all give us ligth. But what exactly is light?
Light is a form of energy that which we can see. It is made up of billions of tiny particles called photons. These photons travel from one place ta another in waves.
The light that we can see consists oi photons that move at a wavelength that makes it visible, and is known
as visible light.
Visible light is actually made up of different colours. Among the different protons that are in visible light, the ones that have the longest wavelength look red to us, and the ones that have shortest wavelength look violet to us.
red, green, and blue are the primary colours of light. Mixing them in various ways will make all other colours, including white. Isn't that amazing?
