A ray in plastic has a critical angle of 44.4 deg when trying to enter air. What is the index of refraction for the plastic?
1 answer:
Answer: 1.43
Explanation:
Given that:
C (critical angle) = 44.4°
n (refractive index of plastic) = ?
Apply the formula n = 1/sineC, the index of refraction for the plastic can be obtained by:
n = 1/sineC
n = 1/sine 44.4°
n = (1/0.6996)
n = 1.43
Thus, the index of refraction for the plastic is 1.43
