Question

What is an electromagnetic wave? Name four types of electromagnetic radiation other than visible light

Answer 1

A wave of photons. Photons are the fundamental particles for EM force, which is one of the four fundamental forces of the universe. The energy carried by each photon is proportional to the frequency of the photon. In math talk, that's E = hf; where h is the constant of proportionality and f is the frequency.

The EM frequency spectrum is very wide. Gamma rays, radar, radio, light, radiant heat, and micro waves (like what you cook with) are in this spectrum, each according to its inherent frequency. Check this out...

"The short wavelength limit is likely to be the Planck length, and the long wavelength limit is the size of the universe itself (see physical cosmology), though in principle the spectrum is infinite. The waves can range from the size of the earth (radio waves) to as small as a atomic nucleus (gamma ray)." [ See source.]

Answer 2

Electromagnetic wave is a self-propagating (it moves itself) wave in space with electric and magnetic components or simply a wave containing electrical and magnetic pulses. These components oscillate at right angles to each other and to the direction of propagation, and are in phase with each other. Electromagnetic radiation is classified into types according to the frequency of the wave: these types include, in order of increasing frequency, radio waves, microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. -Edited (from Wikipedia)
