Question

Space communication involves sending signal emitted from the antenna of the transmitter to the antenna of the receiver. Describe in brief,mentioning frequency range of operation,four different ways by which space communication becomes possible.​

Answer 1

In space, mobile radio, navigation, and broadcasting devices are working on the phenomenon of the transmission of signals.

Explanation:

• The singles travel in the form of bands to far off places.
• The frequency of signals varies from place to place.
• The high-frequency range is 7 3–30 MHz and it is used in horizon communications.
• The very high-frequency range is 8 30–300 MHz and is used in aircraft and radio communication.
• Ultra high-frequency range is 9 300–3000 MHz and i is used in wireless LAN and radio astronomy communications.
• The super high-frequency range is 10 3–30 GHz is used in modern radars and communication satellites.
