PHY 104 Reflection and Refraction of Light Objective Question
Take CBT

Question

The index of refraction (n) of a medium is defined as the ratio of:
Options
A The speed of light in the medium to the speed of light in vacuum (n = v/c).
B The speed of sound in vacuum to the speed of light in the medium (n = v_sound/v_light).
C The speed of light in vacuum to the speed of light in the medium (n = c/v).
Correct Answer
D The wavelength of light in vacuum to the wavelength of light in the medium (n = λ_vacuum/λ_medium).
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 36 defines the index of refraction: 'The index of refraction of the medium is the ratio of the speed of light in vacuum to the speed of light in the medium: n = c/v.'

Hint

Recall the formula for the index of refraction and what 'c' and 'v' represent.
