Critical angle of glass is θ1and the critical angle of water isθ2. Calculate the critical angle for water and glass surface. (μg= 3/2, μw= 4/3)

Dear kaushik

The critical angle is the angle of incidence above which total internal reflection occurs. The angle of incidence is measured with respect to the normal at the refractive boundary. The critical angle θ_c is given by:

critical angle = arcsin(4/3 / 3/2) = 62.73 degres

Please feel free to post as many doubts on our discussion forum as you can. If you find any question Difficult to understand - post it here and we will get you the answer and detailed  solution very  quickly.



All the best.
