    A ray of light is incident on the surface of 47 separation of a medium with the velocity of light at an angle 45° and is refracted in the medium at an angle 30°. What will be the velocity of light in the medium?

    A) \[\text{3}.\text{18}\times \text{1}{{0}^{8}}m/s\]            

    B) \[\text{3}.\text{33}\times {{10}^{\text{8}}}\text{ m}/\text{s}\]

    C) \[\theta =\text{45}{}^\circ \]                     

    D) \[\frac{1}{3}M{{L}^{2}}\]

    Correct Answer: B

    Solution :

                    \[CaC{{l}_{2}}\] \[A\to B,B\to C\] \[C\to A\] \[\upsilon /\text{1}0\]
