Question

Light enters a glass block at an angle of incidence of 46°. The light refracts at an angle of refraction of 26°. What is the refractive index of the glass?
Options
A 0.57
B 0.61
C 1.64
Correct Answer
D 1.77
Correct Answer

Option C is the correct answer.

Detailed Explanation

Using Snell's law: n₁ sin i = n₂ sin r. n₁ = 1 (air). n₂ = sin i / sin r = sin 46° / sin 26° = 0.7193 / 0.4384 = 1.64.

Hint

Use Snell's law: n = sin i / sin r.
