Answer 2

Dear Student,

◆ Answer -

Critical angle for diamond to glass interface = 37.69°.

● Explanation -

# Given -

nd = 2.47

ng = 1.51

# Solution -

Critical angle is that angle of incidence which provides angle of refraction 90°.

Critical angle is calculated by formula -

θc = sin⁻¹(ng/nd)

θc = sin⁻¹(1.51/2.47)

θc = sin⁻¹(0.6113)

θc = 37.69°

Therefore, value of critical angle for diamond to glass interface is 37.69°.

Thanks dear. Hope this helps you...
