Question: What Property Of Radio Waves Makes It Suitable For Satellite Communication?

Microwaves have a high enough frequency to pass through the Earth’s atmosphere to reach geostationary satellites – which orbit high above the equator at a height of 36,000 km.

However, radio waves with a lower frequency are able to reach the low orbit satellites.

Digital signals are used to communicate with satellites.

How radio waves are used for communication?

Radio waves, microwaves, infrared and visible light can all be used for communication. Radio waves – are used to transmit television and radio programs. Microwaves – are used to transmit satellite television and for mobile phones. Infrared – is used to transmit information from remote controls.

Which waves are used for communication by artificial satellites?

Mostly microwaves are used to communicate with the geostationary satellites rather than the satellites that are orbiting in the low orbit. Radio waves are used to communicate with the satellites that are revolving in the lower orbit.

What are the properties of radio waves?

“Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths ranging from 1 millimeter to 100 kilometers.

Why are radio waves used for long distance communication?

An advantage is that this method of communicating does not require wires to transmit information. Medium wavelength radio waves are reflected from the ionosphere, a layer of charged particles in the upper atmosphere, so they can be used for long distance communication.

Why radio waves are used for wireless communication?

When radio stations use similar transmission frequencies the waves sometimes interfere with each other. Medium wavelength radio waves are reflected from the ionosphere so they can be used for long distance communication, but not for communicating with satellites above the ionosphere.

What is an example of a radio wave?

Two examples of electromagnetic radiation (other than radio waves) are: Light — which is the group of electromagnetic radiation you can see with your eyes.

What are the 4 types of satellites?

The satellite must be designed specifically to fulfill its role. There are nine different types of satellites i.e. Communications Satellite, Remote Sensing Satellite, Navigation Satellite, LEO, MEO, HEO, GPS, GEOs, Drone Satellite, Ground Satellite, Polar Satellite.

What type of signals are used in satellite communications?

Satellite communications. Communications satellites are used to send and receive radio signals for television, phone or internet communications. Large concave reflectors called satellite dishes are normally used to send and receive these signals.

Why is there a need for satellite communication?

Communications satellites are used for television, telephone, radio, internet, and military applications. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated geographical points.
