    When the angle of incidence will be equal to angle of refraction for material having negative refraction index?                                        

    A) When angle of incidence = \[{{90}^{o}}\]

    B) When angle of incidence = \[{{0}^{o}}\]

    C) It will vary from material to material

    D) It is never possible

    Correct Answer: B

    Solution :

    Option [b] is correct. Explanation: Like normal refraction, for material having negative refraction index also when the angle of incidence is equal to \[{{0}^{o}}\], then angle of refraction will be equal to angle of incidence i.e. \[{{0}^{o}}\].
