Much higher frequency...Normally the microwave signal is focused by a parabolic disk into a beam that can be pointed ...This sends most of the power in one direction.
No, it is actually a microwave wave.
a microwave is an electromagnetic wave.================Answer #2:A microwave is a radio wave with a wavelengthless than 10 cm (frequency greater than 3 GHz).
Radio waves and microwave.
A short-wavelength radio wave. An electromagnetic wave that is somewhere in between regular radio waves and infrared radiation.

"Microwave" is an electromagnetic wave, and is part of the category of radio waves.A radio wave is "microwave" when its frequency is above 3 GHz (wavelength isless than 10 centimeters).Ironically, the "microwave oven" radiates the food with high power radio wavesat a frequency of 2.5 GHz, so technically, it doesn't use 'microwave' energy at all.
Radio waves are lower frequency.
Nothing, they don't travel through wires.
300E9 corresponds to a frequency of 300 GHz, which falls in the microwave region of the electromagnetic spectrum.
The answer is yes.
gamma ray
Radio waves have less energy than microwaves.
