Question

Radio waves travel at the speed of light, which is 3.00x10^8 m/s. What is the frequency of a radio wave that has a wavelength of 2.5 m?

a. 8.3x10^-9Hz
b. 12Hz
c. 1.2x10^8Hz
d. 7.5x10^8Hz

Answer 1

i dont kno the answer but i know it is c.

➷ Frequency = wave speed/wavelength

frequency = 300000000/2.5

frequency = 120000000

It would be option C.
