Question

Light has wavelength 600 nm in a vacuum. It passes into glass, which has an index of refraction of 1.50. What is the frequency of the light inside the glass?
Options
A 3.3 × 10¹⁴ Hz
B 5.0 × 10¹⁴ Hz
Correct Answer
C 3.3 × 10⁵ Hz
D 5.0 × 10⁵ Hz
Correct Answer

Option B is the correct answer.

Detailed Explanation

The frequency of light does not change when it enters a different medium. f = c/λ = (3 × 10⁸) / (600 × 10⁻⁹) = 5.0 × 10¹⁴ Hz.

Hint

Frequency remains constant during refraction.
