Question

Light travels at a speed of 2.0 × 10⁸ m/s in a glass block. In the glass, the wavelength of the light is 4.0 × 10⁻⁷ m. What is the frequency of the light?
Options
A 2.0 × 10⁻¹⁵ Hz
B 1.3 × 10⁻² Hz
C 80 Hz
D 5.0 × 10¹⁴ Hz
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

f = v/λ = (2.0 × 10⁸) / (4.0 × 10⁻⁷) = 5.0 × 10¹⁴ Hz.

Hint

Use f = v/λ.
