A) 10 MHz
B) 1 kHz
C) 1 MHz
D) 10 kHz
Correct Answer: C
Solution :
Here: velocity of radio waves \[=3\times {{10}^{5}}km\text{/}\sec \] \[=3\times {{10}^{8}}km\text{/}\sec \] and wavelength \[\lambda =300\,m\] \[frequency\,f=\frac{velocity\,of\,radiowaves}{wavelength}\] \[=\frac{3\times {{10}^{8}}}{300}={{10}^{6}}Hz=1MHz\]You need to login to perform this action.
