The FM station KDUL broadcasts music at 99.1 MHz. Find the wavelength of those waves.

wavelength * frequency = wavespeed.
In this case, the wavespeed is the speed of propagation of electromagnetic radiation (i.e., the speed of light). We'll assume the question is asking for the wavelength of these waves in air. The difference between the speed of light in air and the speed of light in a vacuum is negligible, so we can let the wavespeed = 2.998*10^8 m/sec. We are told the frequency is 99.1*10^6 Hz (1 Hz = 1 sec^-1) so:
wavelength = (2.998 *10^8 m/sec)/(99.1*10^6 sec^-1)
wavelength = 3.025 meters

I don't have a formula for this, but I did find a conversion table:
99.1 MHz = 0.0003 cm wavelength

v = fλ ("v" is the velocity of the wave, "f" is the frequency of the wave, and "λ" is the wavelength of the wave)
λ = v/f
λ = (3.0 x 10^8)/(99.1 x 10^6)
λ = 3.0 m
