Question

Suppose you are standing 201 m from a radio transmitter. What is your distance from the transmitter in terms of the number of wavelengths for the following conditions?

(a) The station is broadcasting at 1150 kHz (on the AM radio band)? (1 kHz = 1 multiplied by 103 Hz.)

?? wavelengths


(b) The station is broadcasting at 98.1 MHz (on the FM radio band)? (1 MHz = 106 Hz.)

??wavelengths

Answer 1

c=wavelength x frequency.
3 x 10^8 = 1.150 x 10^6 Hz x wavelength.
Solve for wavelengths)in meters).
Then 200/signal wavelength = # wavelengths.

Answer 2

260 Hz/ms
