Study the following four experimental setups by four students A, B, C and D showing the incident ray to trace the path of a ray of light through a glass slab. Which of these will get the best result ?
(a) (A) (b) (B) (c) (C) (d) (D)
option B is correct.
Experiment II has largest angle of incidence , due to which lateral displacement between incident ray and emergent ray would be maximum.
