Here's why:

* Electromagnetic radiation is a form of energy that travels as waves. It doesn't consist of particles with mass like protons or electrons.

* It's made up of oscillating electric and magnetic fields. These fields are disturbances in space that carry energy but have no mass.

Examples of electromagnetic radiation include:

* Radio waves: Used for communication.

* Microwaves: Used for heating food.

* Infrared radiation: Used in heat sensing devices.

* Visible light: What we see with our eyes.

* Ultraviolet radiation: From the sun, can cause sunburn.

* X-rays: Used in medical imaging.

* Gamma rays: The most energetic form, produced by nuclear reactions.
