Question

A student very cautiously traces the path of a ray through a glass slab for different values of the angle of incidence. He then measures the corresponding values of angle of refraction and the angle of emergence for every value of the angle of incidence.

On analyzing these measurement of angles, his conclusion would be..

Please answer..

Answer 1

Answer b is correct

As slab is denser ray deviates towards normal but same deviation in opposite direction is observed when ray emerges Out Of The Slab and angle of incidence and angle of emergence are parallel hence have same angle but greater than r
