Microwaves are electromagnetic waves, just like visible light or sound waves. Like sound waves, they can display constructive or destructive interference. Two microwave beams, having slightly different frequencies, will produce a beat pattern, as shown in this video, with the beat frequency equaling the difference of the frequencies of the two waves that are beating.
Thanks for the video man really helped, but careful with your youtube name, could be misinterpreted :/
