Question

The maximum distance upto which TV transmission from a TV tower of height h can be received is proportional to which of the following?

(a) h^1/2

(b) h

(c) h^3/2

(d) h^2

I got this question in a job interview.

Question is from Communication Systems topic in chapter Communication Systems of Physics – Class 12

Answer 1

Right choice is (a) h^1/2

Explanation: The maximum distance upto which TV transmission from a TV tower of height h can be received is proportional to h^1/2.

d = √2Rh.

d ∝ h^1/2.
