microwaves

benefits:

a. Microwaves are used in the analysis of the structure of atoms and molecules

b. This wave is also used on the radar with a frequency of about 10 ^ 10 Hz and a wavelength of several centimeters

c. These waves are easily reflected by objects measuring a few meters as cars, airplanes, or rockets because their wavelengths are included in the short boundary

d. Microwaves can penetrate the layers of the ionosphere so that is widely used for communication between the continents with the help of satellites.
