Why you use microwaves in satellite communication?

Answer 1

Microwaves are used in communications because of their shorter wavelength and smaller antennae. This allows them to be more directional than lower frequency radio waves. The Microwave spectrum also has more bandwidth than the radio spectrum. They also waste less energy than Radio Waves

Answer 2

The radio waves(this is what i think) are so intense that is cooks the food/whatever's in it.that's why you NEVER put metal in the microwave or it will break.This would happen because the metal reflects the waves back to the microwave,the waves are so intense that the microwave gets broken.

Answer 3

Radio waves being electromagnetic does not need any material medium to get transferred. With high frequency known to be carrier wave this is able to reach far distance. But this carrier wave is to carry the signal to be communicated. The signal may be audio or video or any other digital. This would modulate the carrier wave by changing any of the characteristic of the carrier wave namely amplitude, frequency or phase.

The modulated carrier wave as it gets transmitted will be received at a far place and demodulated or the signal is detected right from it. This is how radio waves now a days known as micro waves are so helpful in communication systems.

Answer 4

High enough frequency to carry the information, long enough wavelength to penetrate the atmosphere. They do not rapidly disperse in the atmosphere so the power does not need to be very high to reach a distant point. They can be focused by a suitable dish to increase the reception of low power signals. They can be modulated to carry the signal and are resistant to interference.

Answer 5

The thing about radio waves is: They don't need wires, pipes, or fibers to travel

through, so you don't need to dig trenches or put up poles all along the way.

We know how to get the information off of them even after they travel hundreds,

thousands, or even millions of miles, and they're pretty easy and cheap to make.

Answer 6

radio waves transmmit in a particular frequency when a receiver set on particular frequency that catch the information or data of that waves may be contain

Answer 7

Radio waves are used for communication and in MRIs (Magnetic Resonance Imaging)

Microwaves are used in communication as well as in the microwave oven to heat up things.

Answer 8

Radio waves are fast communications, speed of light.

Answer 9

Line of sight radio,

and satellite cell phones.
