Question:

The maximum distance upto which TV transmission from a TV tower of height $h$ can be received is proportional to:

Options:

$h^{1⁄2}$

$h$

$h^{3⁄2}$

$h^2$

Correct Answer:

$h^{1⁄2}$

Explanation:

The maximum distance the signals travel is $ d = \sqrt{2hR}$

$\Rightarrow d \propto \sqrt{h}$

Thus the maximum distance up to which TV transmission from a TV tower of height h can be received is proportional to the square root of h.
