PHY 104 Reflection and Refraction of Light Objective Question
Take CBT

Question

Based on Table 32-1 on page 36, in which of the following materials does light travel the slowest?
Options
A Water (n = 1.33)
B Crown glass (n = 1.52)
C Diamond (n = 2.42)
Correct Answer
D Ethyl alcohol (n = 1.36)
Correct Answer

Option C is the correct answer.

Detailed Explanation

The index of refraction (n) is inversely proportional to the speed of light (v) in the medium (n = c/v). Therefore, a higher index of refraction means a slower speed of light. Among the given options from Table 32-1, Diamond has the highest index of refraction (2.42), so light travels slowest in Diamond.

Hint

Remember the relationship: n = c/v. A larger 'n' implies a smaller 'v'.
