ELECTROMAGNETIC WAVES HAS LONGEST WAVELENGTH

Answer:

Radio waves

Explanation:

This is the following explanation about radio waves. The longest wavelength is that of radio waves, while the shortest wavelength is that of gamma rays. Radio waves are a form of electromagnetic radiation with wavelengths longer than infrared radiation in the electromagnetic spectrum. The frequency of radio waves range from 300 gigahertz (GHz) to 30 hertz (Hz). Radio waves, like other electromagnetic waves, travel at the speed of light in a vacuum and at a somewhat slower speed in the Earth's atmosphere. Charged particles undergoing acceleration, such as time-varying electric currents, produce radio waves. Lightning and celestial objects generate naturally occurring radio waves.
