Answer:
n = 1.4266
Explanation:
Given that:
refractive index of crystalline slab n = 1.665
let refractive index of fluid is n.
angle of incidence θ₁ = 37.0°
Critical angle
According to Snell's law of refraction:
At point P ;
Therefore:
Then maximum value of refractive index n of the fluid is:
n = 1.4266
