In communication system, the range for line of sight propagation in case of earth is 'd', for the height of antenna (h). If 'h' is doubled then the new range is
$\frac{\mathrm{d}}{\sqrt{2}}$
$\frac{\sqrt{2}}{\mathrm{~d}}$
$\frac{\mathrm{d}}{2}$
$\sqrt{2} \mathrm{~d}$
Solution
We know, $d^{\wedge} 2 \alpha h$ d $\propto$ sqrt(h)
so when height is doubled range is sqrt(2) times original value
