Question

What is the relation between the critical angle of glass-air and glass-water interface?

Answer 1

Answer:

The critical angle of glass in air is 41.8. What is the critical angle of glass in water when the refractive index of water is 1.33? How do I calculate the critical angle for the glass-water interface if the refractive index of glass is 1.6 and water is 1.33?
