Please solve 2 2. 3. 4 Electromagnetic Wave, Cathode Rays and X-Rays 629 Calculate the frequency of radio wave of yavelength 300 metre. Ans. 1 MHz. A radio station broadcasts at 1200 metre. Calculate the frequency of the emitted radio wave. Ans. 250 KHz. of a radio wave which is transmitted on a

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.
