Question

A popular radio station, NPR, transmits a signal that is has a wavelength of 3.38 m. What is the frequency of this signal? Remember that the speed of light is 299,792,458 m.

Answer 1

88,695,993.49Hertz

Explanation:

The formula for calculating the velocity of wave is expressed as;

v = fλ

f is the frequency

λ is the wavelength

f = v/λ

Given

v = 299,792,458 m/s

λ = 3.38m

Substitute and get the frequency f

f = 299,792,458 /3.38

f = 88,695,993.49Hertz

Hence the frequency of the signal is 88,695,993.49Hertz
