Question

Refractive index of diamond is 2.42 and that of glass is 1.5. Calculate the critical angle for diamond-glass surface.

Open in App

Solution

Refractive index of diamond = $n_{1}$ = 2.42

Refractive index of glass = $n_{2}$ = 1.5

Critical angle = c

Therefore, $S i n c$ = $\frac{n_{2}}{n_{1}}$ = 0.6198

c = ${38.3}^{0}$
