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
Verified Correct Answer: D.
Physical Principles & Numerical Solution
f = \(\frac{V}{\lambda} = \frac{3 \times 10^8}{150}\)
= 2.0 x 10\(^6\) Hz
