Em wave microwave

WebMicrowaves are the highest-frequency electromagnetic waves that can be produced by currents in macroscopic circuits and devices. Microwave frequencies range from about 10 9 Hz to nearly 10 12 Hz. Their high frequencies correspond to short wavelengths compared with other radio waves—hence the name “microwave.” WebFeb 20, 2004 · Electromagnetic (EM) waves are all around us, though we can only see a small range of them, they can be used to cook our food, allow cell phones to communicate with each other, and permit us to see inside the human body.

WebMay 6, 2024 · Microwaves, for example, can be reflected off metallic surfaces. This seems counter-intuitive, since the metal's electrons could interact with the electric field component of the EM wave and absorb it. In fact, you can use a metal grid to polarise microwaves, and there the metal absorbs the microwaves.

WebIn 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.

WebThe electromagnetic spectrum is a series of frequencies ranging from radio waves to microwaves, visible light, X-rays, and gamma rays.
