A ray of light travelling in air is incident on the surface of glass slab at an angle of 40^(@) . If the ray is deviated through 18^(@) , determine critical angle for the glass-air interface.

Draw ray diagrams for incident rays at angle of incidence less than critical angle and more than critical angle?

A ray of light travelling from glass to air is incident at 50^(@) from the glass air boundary . What is the angle of deviation if the critical angle is 42^(@) ?

A ray of light travelling through air is incident on the surface of water in a lake . If the ray is inclined at 30^@ with the surface and if the refractive index of water is 4/3 then the angle through which the ray deviates is
