Question

4. A ray of light in incident in glass on a plane glass-air boundary and makes an angle of 30°
with the normal to the boundary. Calculate the angle through which the ray is deviated on
entering the air. (Refractive index of glass with respect to air = 1.5.)​

Answer 1

Answer:

the refracted angle will be30 degree angle

Explanation:

bcz the incident angle is equal to the reflected angle
