An FM radio station transmits radio signals that have a wavelength of 3.2m. Where would you have to adjust your tuner in order to pick up its music? Note: FM waves are measured in MHZ

I have no idea where to go with this...

Thank you :)

1. Scott

frequency = speed / wavelength

f = c / 3.2 m = 93.7 MHz

Thank you :) is c=300m/s a relatively constant value?

3. Scott

c is the speed of light
(like E = m c^2)

3x10^8 m/s

Thanks a ton!! :)
