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: D. 2.0 x 106Hz
Explanation
f = \(\frac{V}{\lambda} = \frac{3 \times 10^8}{150}\)
= 2.0 x 10\(^6\) Hz
