Here's a breakdown:

* Electromagnetic radiation is a form of energy that travels through space as waves.

* These waves have different wavelengths, and the Sun emits a wide range of wavelengths, including visible light, infrared radiation, and ultraviolet radiation.

* The visible light is what we see as sunlight.

In simpler terms: The Sun is like a giant ball of fire that sends out energy in the form of waves. These waves reach Earth and give us light and heat.
