Q160 / 160 · AP EAMCET 2019 (21 Apr Shift 2) · Physics

The frequency suitable for beyond-the-horizon communication using sky waves is

A
$10^{12} Hz$
B
$10^{9} Hz$
Correct answer
C
$10^{7} Hz$
D
$10^{4} Hz$

Solution

The sky wave acts as a radio wave, thus, the suitable
frequency suitable for beyond the horizon communication
using the sky wave is

10 MHz

or $\left(10^{7} \mathrm{~Hz}\right)$.

Hence, the correct answer is option: 'C'.
