Explain that microwaves are better carriers of signals than radio waves?

(A) : The microwaves are better carriers of signals than radio waves. (R) : The electromagnetic waves do not require any medium for propagation.

Assertion : Microwaves are better carrier of signals than optical waves Reason : Microwaves move faster than optical waves.

Assertion : Microwaves are better carrier of signals than optical waves Reason : Microwaves move faster than optical waves.

Give a reason to show that microwaves are better carries of signals for long range transmission than radio waves.

A radio transmitter, microwave transmitter and a mi crowave receivers are placed in a hilly area. Will the radio receiver in the house get the signal from the radio transmitter? Justify

(A) : Propagation of electromagnetic waves as microwaves is better than that as sky waves. (R) : Microwaves have frequencies 100 GHz to 300 GHz with very good directional properties.
