Nothing, they don't travel through wires.
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.
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.
Scientists group electromagnetic waves into categories according to their wavelength. Technically a radio wave has a longer wavelength then a microwave but that's the only fundamental difference. They are both electromagnetic waves.
No. Microwave is a radio wave, which is an electromagnetic wave.No, its actually an electromagnetic waves, just like X-rays and visible light...electromagnetic waves dont need to go through medium ( solid, liquid, gas).
It works by bombarding the food inside it with microwave (radio wave) energy. This causes the molecules inside the food to become excited and generate heat.
