Microwaves and radio waves are used to communicate with satellites.
Microwaves pass straight through the atmosphere and are suitable for communicating with distant geostationary satellites, while radio waves are suitable for communicating with satellites in low orbit.
Which wave is used in satellite?
Radio waves are used to carry satellite signals. These waves travel at 300,000 km/s (the speed of light).
Which wave is 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.
What kind of waves do GPS use?
GPS receivers work by receiving signals from the satellites – nothing needs to be sent. The signals are sent from the satellites at microwave frequencies of 1.22 and 1.57 GHz.
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 are 3 uses of satellites?
The uses of Artificial satellites are:
- They are used for communication purpose.
- Carry instrument or passengers to perform experiments in space.
- For Weather Forecasting System.
- For GPS (Global Positioning System)
What are waves used for?
Naturally occurring radio waves are made by lightning or by astronomical objects. Artificially generated radio waves are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, communications satellites, computer networks and innumerable other applications.
What are the uses of waves?
Radio waves are used for communication such as broadcasting television and radio, communications and satellite transmissions. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction.
What is long distance communication?
Long-Distance Communications. Telephone, telegraph, phototelegraph, and television signals are transmitted simultaneously over long distances over air, cable, and radio communications lines in which hundreds or thousands of independent communications channels are formed by multiplexing communications lines.
