Introduction
 Have you ever heard of electromagnetic spectrum?

You actually know more about it than you may think!

The electromagnetic (EM) spectrum is just a name that scientists give to types of radiation when they want to talk about them as a group.

Radiation is energy that travels and spreads out as it goes-- visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays. Hotter, more energetic objects and events create higher energy radiation than cool objects. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays.

Let's look into this topic with more depth.
