A) 50 kHz
B) 100 kHz
C) 500 kHz
D) 200 kHz
Correct Answer: D
Solution :
Wavelength of radio transmitter \[\lambda =1500m\] The frequency of radio transmitter is \[n=\frac{c}{\lambda }=\frac{3\times {{10}^{8}}}{1500}\] \[=200\times {{10}^{3}}=200\text{ }kHz\]You need to login to perform this action.
