What do all the electromagnetic waves have in common?

The electromagnetic spectrum. Electromagnetic waves carry transverse vibrations in electrical and magnetic fields, not vibrating particles. In a vacuum, all electromagnetic waves travel at approximately 3 x 108 m/s - the fastest speed possible.

Besides, which has the highest frequency in electromagnetic waves?

Radio waves have the lowest frequencies and longest wavelengths, while gamma waves have highest frequencies and shortest wavelengths. The wavelengths vary across the electromagnetic spectrum from about 10–15 m to more than 104 m.

How many electromagnetic waves are there?

The different types of electromagnetic radiation shown in the electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible light, ultraviolet radiation, X-rays, and gamma rays. The part of the electromagnetic spectrum that we are able to see is the visible light spectrum.
