Question

Short Note

Answer the following question.
Why a signal transmitted from a TV tower cannot be received beyond a certain distance? Write the expression for the optimum separation between the receiving and the transmitting antenna.

Solution

The signal transmitted from a TV tower cannot be received beyond a certain distance because of the curvature of the earth. The expression for the optimum separation between the receiving and transmitting antenna:

`d = sqrt(2hR)`

d: Optimum separation.
h: Height of the antenna  
R - Radius of the curvature of Earth. 

  Is there an error in this question or solution?
