About 150 years ago, James Clerk Maxwell , an English scientist, developed a scientific theory to explain electromagnetic waves. He noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves.

Read moreHow electromagnetic waves are generated?
Electromagnetic waves are formed when an electric field (which is shown in blue arrows) couples with a magnetic field (which is shown in red arrows). Magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave.
Read moreHow does NASA use electromagnetic waves?
NASA utilizes the VHF band by airborne sensors to study the thickness of sea ice . NASA astronauts use UHF systems as backups for their voice communication systems. NASA also used these frequencies to remotely sense the Earth’s surface (e.g. soil moisture with the SMAP mission) and atmosphere.5 Eyl 2018
Read moreWhat does NASA use the electromagnetic spectrum to study?
NASA’s scientific instruments use the full range of the electromagnetic spectrum to study the Earth, the solar system, and the universe beyond . When you tune your radio, watch TV, send a text message, or pop popcorn in a microwave oven, you are using electromagnetic energy.
Read moreDo astronomers use electromagnetic spectrum?
Astronomers use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space . Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study.
Read moreWhat are the 7 regions of electromagnetic spectrum?
In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves . Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
