Please solve 2

2. Calculate the frequency of radio wave of wavelength 300 metre. 

Dear student,
I am answering question no 2.

given wavelength=300 meter,
We know speed of light = 3×10⁸ m/s
So frequency = (speed of light)/ (wavelength)
=》 frequency = (3×10⁸)/(300) =1×10⁶ Hz. = 1 MHz.

Hope it helps,
Regards.
