Answer 2

Hello buddy..

The radiation that we receive from sun is in the form of Electromagnetic wave..

Radiant energy is the energy of electromagnetic waves. It is a form of energy that can travel through space. For example, we receive the heat from the sun, which is located very far from the earth via radiation. The sun's heat is not transmitted through any solid medium, but through a vacuum. This is possible by electromagnetic waves.

Before we go any further, let us understand what electromagnetic waves are.

Each time static energy from electric and magnetic force come together, they induce an electric field around them. 

An example of electric static force is the shock you get when you hold a metal door knob. 

Hope it helps you buddy...
