From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action between particles that have an electric charge) surround us. But did you know that there's ...

Figure caption, Each region of the electromagnetic (EM) spectrum has a range of wavelengths associated with it. Radio waves have the longest wavelengths and gamma rays have the shortest wavelengths.

The only thing that differentiates one type of electromagnetic radiation from any other is the energy carried by its photons. There's lots to discover in the electromagnetic spectrum. Here's a ...

After emitting an alpha or beta particle, the nucleus will often still be ‘excited’ and will need to lose energy. It does this by emitting a high energy electromagnetic wave called a gamma ray.
