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
- 4.50 x 1010Hz
- 5.0 x 109Hz
- 4.5 x 109Hz
-
2.0 x 106Hz
The correct answer is: D
Explanation
f = \(\frac{V}{\lambda} = \frac{3 \times 10^8}{150}\)
= 2.0 x 10\(^6\) Hz
