Answer:
1.5
Explanation:
Data obtained from the question include:
C (critical angle) = 41.8°
n (refractive index od benzene) =?
Using the formula n = 1/sineC, the refractive index of benzene can be achieved as shown below:
n = 1/sineC
n = 1/sine 41.8°
n = 1.5
Therefore, the refractive index of benzene is 1.5
