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]
A
3.0 x 1014 Hz
B
6.0 x 1014 Hz
C
6.0 x 1012 Hz
D
2.5 x 1014 Hz
Verified Correct Answer: B.
Physical Principles & Numerical Solution
f = \(\frac{\text{c}}{\lambda}\)
f = \(\frac{ 3 \times 10^8}{500 \times 10^{-9}}\)
= 6.0 x 10\(^{14}\) Hz
