Question

Calculate the critical angle for a glass medium.If the refractive index is 1

Answer 1

Answer:

Question should be Calculate the critical angle for a glass-air medium.If the refractive index is 1

Explanation:

critical angle  = sin-1 (nr/ni) = sin-1 (nr/ni)

critical angle   = sin-1 (1.000/1.52) = 41.1 degrees
