Question

a radio station broadcast at a wavelength 400m find the frequency of the ratio waves transmitted if the speed of ratio waves air is 3*108​

Answer 1

Answer:

c = 3 * 10 ^ 8       λ = 400 m

f = ?

we know the formula c = f *  λ

Substituting the value ,

3 * 10 ^ 8 = f * 400

=> f = ( 3 * 10 ^ 8)/ 400

=> f = 7.5 * 10^5 Hz
