Q. The velocity of electromagnetic waves in free space is $3 times 10^{8} ,m / sec$. The frequency of a radio wave of wave length $150, m$, is

In This post you will get answer of Q.
The velocity of electromagnetic waves in free space is $3 times 10^{8} ,m / sec$. The frequency of a radio wave of wave length $150, m$, is

Solution:

Given: Velocity of electromagnetic waves in free space $(v)=3 times 10^{8}, m / ,sec$ and wavelength $(lambda)$

$=150, m .$ We know that frequency $(f)=frac{v}{lambda}=frac{3 times 10^{8}}{150}$

$= 2 times 10^{6} ,Hz =2, MHz$
