Question

a ray of light travelling in a water medium falls on water -air interface at an angle 45 with the vertical.will it be possible by the ray of light to come out of water surface

Open in App

Solution

Yes.The ray of light will be able to come out as the angle of incidence at the water- air interface is 45⁰ which is less than the critical angle for the given pair of media.
