The critical angle for glass air interface is `C` and for glass water interface ic `C'`. How are `C and C'` related ?

The critical angle for glass air interface is C and for glass water interface is c' . How are C and C' related ?

Calculate the critical angle for a glass air interface, if a ray of light incident in air on the surface is deviated through 15^@ , when its angle of incidence is 40^@ .

For glass-air interface,the critical angle is C.Will the critical angle for glass-water interface be greater or less than C?

A ray of light travelling in glass having refractive index _(a)mu_(g)=3//2 is incident at a critical angle C on the glass air interface. If a thin layer of water is poured on glass air interface, then what will be the angle of emergence of this ray in air when it emerges from water air inteface?

The critical angle of a medium-air interface is 30^(@) . The refractive index of the medium is

Determine the critical angle for a glass interface, if a ray of light, which is incident in air on the surface is deviated through 15^@ , when its angle of incidence is 40^@ .
