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?
- 7500m
-
300m
- 75m
- 15m
The correct answer is: B
Explanation
\(\lambda\)1F1 = \(\lambda\)2F21500 x 200000 = 1000000 x \(\lambda\)2
\(\lambda\)2 = 300m
