# Give Two Examples of Communication System Which Use Space Wave Mode. a Tv Tower is 80 M Tall. Calculate the Maximum Distance Upto Which the Signal Transmitted from the Tower Can Be Received. - PUC Karnataka Science Class 12 - Physics

#### Question

Give two examples of communication system which use space wave mode.
A TV tower is 80 m tall. Calculate the maximum distance upto which the signal transmitted from the tower can be received.

#### Solution

Examples of communication systems which use space wave mode are

(iii) Satellite communication

(Any two examples can be taken)

The maximum distance up to which signals can be received, d = sqrt(2R_Eh_T)

=sqrt(2 xx 6400000 xx 80)

= 32000 m

= 32 km

Hence, the maximum distance up to which the transmitted signal can be received is 32 km.

Is there an error in this question or solution?
