Question

Inference / Conclusion:
Initially, as the angle of incidence increases gradually, the angle of deviation decreasrs but
after certain minimum value of incident angle, increases with the increase in the angle of incidence​

Answer 1

Answer:

If we gradually increase the angle of incidence the angle of deviation first decreases array of light passing through the prism course in this process there is a variation in angle of deviation with the angle of incidence.
