microwave

(electromagnetic radiation, frequency 300MHz to 300GHz)

Microwave is electromagnetic radiation (EMR) with wavelength in the range of 1mm to 1m (frequency 300MHz to 300GHz). It comprises the shortest radio waves, adjacent to infrared.

The terms microwave astronomy and microwave radio astronomy are occasionally used and the more common term, millimeter astronomy spans the border between microwave and infrared. The atmosphere blocks much microwave EMR from reaching Earth, and space observatories have been used. However, the long-wavelength end of microwave is within the radio atmospheric window, multiple narrow windows allow some shorter microwaves through, and high-altitude observatories allow microwave telescopes to sense more signal.

Some microwave sources, i.e., the subjects of microwave astronomy:
