Question

What is the frequency of radio waves with wavelength of 20m?

Given:
Wavelength=20m
Speed of light (C) =3×10^8

Somebody help! I don't know what's the formula

Answer 1

The formula is: Frequency = speed / wavelength.

Answer 2

14989622.9 Hz

I think...

speed divided by wavlength is frecuency. Not sure though
