Aray of light travelling in water is incident on its surfac open to air. The angle of incident is theta, which is less than the critical angle. Then there will be :

Answer»

only a REFLECTED ray and no refracted ray
only a refracted ray and no reflected ray
a reflected ray and a refacted ray and the angle between them WOULD be less than `(180^(@) - 2theta)`

SOLUTION :(c )
