How are microwaves made science
WebRadio and microwaves are usually described in terms of frequency (Hertz), infrared and visible light in terms of wavelength (meters), and x-rays and gamma rays in terms of energy (electron volts). This is a scientific convention that allows the convenient use of units that have numbers that are neither too large nor too small.

It's true: microwave emissions from outer space help give a peek … WebMicrowaves are sometimes considered to be very short radio waves (highfrequency and high-energy radio waves). Some important properties of microwaves are: They are reflected by metal surfaces. They heat materials if they can make atoms or molecules in the material vibrate. The amount of heating depends on the intensity of the microwave ...
WebMicrowaves act as high frequency electric fields and will generally heat any material containing mobile electric charges, such as polar molecules in a solvent or conducting ions in a solid. Polar solvents are heated as their component molecules are forced to rotate with the field and lose energy in collisions. WebRadio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction. These properties …
