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 the speed of light in vacuum (c) to the speed of light in the medium (v). Which of the following equations correctly represents this relationship?
Options
A <i>n</i> = <i>v</i> / <i>c</i>
B <i>n</i> = <i>c</i> ⋅ <i>v</i>
C <i>n</i> = <i>c</i> / <i>v</i>
Correct Answer
D <i>n</i> = 1 / (<i>c</i> ⋅ <i>v</i>)
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 36 states: '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

The index of refraction is a measure of how much light slows down in a medium compared to a vacuum.
