Radio.
electromagnetic radiations are formed due to the disturbances in electric and magnetic fields which are perpendicular to each other.
Electromagnetic spectrum is formed due to the difference of wavelengths and frequency of electromagnetic radiations as they are orderly distributed.
It blocks the UV part of the electromagnetic radiation. These are harmful radiations.
Yes they can. They are a form of electromagnetic rays and all types of electromagnetic radiations can travel in vacuum
... the ones we call "gamma rays".
The visible spectrum between red and violet.
Radio waves have the lowest frequency among electromagnetic radiations.
X-rays (electromagnetic) and beta/alpha (particulate) are some examples of radiation.
Electromagnetic radiation has both wave and particle properties. There's not really a "why" involved, that's just the way the universe is.
Beta rays are electrons, not electromagnetic.
No, gamma rays have the shortest wavelength among all electromagnetic radiations. They have the highest frequency and highest energy in the electromagnetic spectrum.
