what will be the value of the angle of refraction,when the angle of incidence is 0
rohitsingh2909:
The formula for angle of refraction is n1 (sinx)= n2 (siny) , where x and y being angle of incidence and refraction respectively. So here angle of incidence is zero . Sin0=0, hence angle of refraction is also zero.

Refraction is zero because the light beam entering the medium will be at 90 degrees to its surface, so there is no refraction.

90 degrees without reflection
