Question

the critical angle of glass air interface is 42°. what will happen if the angle of incidence falling in the glass is 48°?​

Answer 1

Answer:

Their kinetic energies are the same K. E. = W = Fxd Since retarding force is the same, they will travel the same distance before coming to stop. 48. Coefficient of viscosity 49. Refractive index of a medium ... This angle of incidence is greater than the critical angle of glass-air interface which is about 42°. A Hence, total internal ...
