Please can you help with a simple wavelength problem?

Question

The FM station KDUL broadcasts music at 99.1MHz. Calculate the wavelength of this station.

Answer 1

300 / 99.1 meters

Answer 2

For all electromagnetic radiation, including FM radio, the following applies:



λ = c/f



where

λ is wavelength in cm

c is the speed of light = 3 x 10^10 cm/s

f is the frequency = 99.1 x 10^9 Hz



λ = (3 x 10^10) / (99.1 x 10^9) = 0.30 cm = 3 mm

Answer 3

1000 mHz = 1 ghz.

1 ghz = 11.7 inches wavelength. or rounded to one foot.  you figure it out.
