The wavelength of signals from a radio transmitter is 1500mm and the frequency is 200kHz. What is the wavelength for a transmitter operating at 100kHz?
-
A.
7500m -
B.
300m -
C.
75m -
D.
15m
Correct Answer: Option B
Explanation
(lambda)1F1 = (lambda)2F2
1500 x 200000 = 1000000 x (lambda)2
(lambda)2 = 300m
