368888 Read the Assertion and Reason carefully to mark the correct options given below:
Assertion :
EM waves used for optical communication have longer wavelengths than that of microwave, employed in Radar technology.
Reason :
Infrared EM waves are more energetic than microwaves, (used in Radar).

368889 Assertion :
It is necessary to use satellite for long distance T.V. transmission.
Reason :
The television signals are low. frequency signals.

368890 In the line of sight communication maximum separation between two antennas is \(45\;km\). FInd the height of each antenna assuming they are of same height and radius of earth is \(6400\;km\)

368891 Assertion :
The surface (ground) wave propagation is used for radio broadcasting.
Reason :
The surface waves travel directly from transmitting antenna to receiver antenna through atmosphere.

368892 Assertion :
Satellite for remote sensing.
Reason :
Such satellite shall be in polar orbit.
