Question

Which one has greater critical angle diamond or glass?

Answer 1

glass has greater critical angle than diamond.

Answer 2

Hello mate,

◆ Answer-
Glass has larger critical angle than diamond.

◆ Critical angle-
- It's that angle of incidence which provides angle of refraction 90°.
- After angle of incidence goes over critical angle, incident ray completely undergoes total internal reflection.
- Critical angle can be calculated as -
sinθ = 1/μ

# For glass and diamond -
As refractive index of glass (μg=1.5) is smaller than that for diamond (μd=2.62), glass has larger critical angle.

Hope this helps you...
