The frequency of a radio wave varies inversely as its wavelength.
If a 50-meter wave has a frequency of 6,000 kilohertz, what is the wavelength of a wave that has a frequency of 400 kilohertz?
Round your answer to the nearest meter.
:
let w = wavelength of a frequency of 400 kc
An inverse ratio equation
=
cross multiply
400w = 50 * 6000
400w = 300000
w = 300000/400
w = 750 meters
