Answer: 1.50
Explanation:
Given that:
C (critical angle) = 41.7°
n (index of refraction in benzene) = 2.42
n (index of refraction in benzene) = ?
To get the index of refraction in benzene, Apply the formula n = 1/sineC,
n = 1/sine41.7°
n = 1/sine 41.7°
n = (1/0.6652)
n = 1.50
Thus, the index of refraction for the ray in benzene is 1.50
