  • question_answer
    Direction: Read the passage carefully and answer the following question. The path of a light ray from air to two different media A and B for a given angle of incidence is as shown.
     
    If angle of incidence is increased in both media, then angle of refraction will

    A) Increase

    B) Decrease

    C) Remain same

    D) Become zero in medium A and will remain same in medium B.

    Correct Answer: A

    Solution :

    Refractive index \[n=\frac{\sin i}{\sin r};\] where i and r are angle of incidence and angle of refraction and \[\frac{\sin i}{\sin r}\] for a particular medium remains same  i.e., constant.
