A radio wave has a wavelength of 150m. If the velocity of radio waves is free spaces is 3 x 10\(^8\) ms\(^{-1}\), calculate the frequency of the radio wave
A.
4.50 x 1010Hz
B.
5.0 x 109Hz
C.
4.5 x 109Hz
D.
2.0 x 106Hz
Correct Answer: Option D
Explanation
f = \(\frac{V}{\lambda} = \frac{3 \times 10^8}{150}\)
