Light has wavelength 600 nm in free space. It passes into glass, which has an index of refraction of 1.50, what is the frequency of the light inside the glass?
(A) 3.3 × 1014Hz
(B) 5.0 × 1014 Hz
(C) 3.3 × 105 Hz
(D) 5.0 × 105 Hz
Correct option**(B) 5.0 × 1014 Hz**
Explanation:
We know that, Frequency = Speed of light of air/Wavelenght of light in air
