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 reflected ray and no reflected ray
C. a reflected ray and refracted ray and the angle between then would be less than `180^(@)-2theta`
D. a reflected ray and a refracted ray and the angle between then would be greater than `180^(@)-2theta`

Answer

C

Explanation

Since `theta lt theta_(C)`, both reflection and refraction will take place. From the figrue we can see that angle between reflected and refracted rays is less than `180^(@)-2theta`.
