A ray of light travelling in water is incident on its surface open to air. The angle of incidence is `theta`, which is less than the critical angle. Then there will be

Options

A. only a reflected ray and no refracted ray
B. only a refracted ray and no reflected ray
C. a reflected ray and a refracted ray and the angle between them would be less than `180degree-2theta`
D. a reflected ray and a refracted ray and the angle between them would be greater than `180degree-2theta`

Answer

C

Explanation

The ray is partly reflected and partly refracted `angleMOB=180-2theta`
But the angle between refracted and reflected rays is `angle`POB. Clearly is `angle`POB is less than `angle`MOB.
