If a light wave has a wavelength of 500nm in air what is the frequency of the wave?
[c = 3 x 10\(^8\) ms-1]
- 3.0 x 1014 Hz
-
6.0 x 1014 Hz
- 6.0 x 1012 Hz
- 2.5 x 1014 Hz
The correct answer is: B
Explanation
f = c/λ
| ∴ f = | c | = | 3 x 108 |
| λ | 500 x 10-9 |
=6.0 x 1014 Hz
There is an explanation video available .
