Question

When light rays are incident on a prism at an angle of ${45}^o$, the minimum deviation is obtained. If the refractive index of the material of the prism is $\sqrt{3}$, then the angle of prism will be

• A. $2\times {\sin }^{-1}\frac{1}{\sqrt{6}}$
• B. ${45}^o$
• C. ${60}^o$
• D. ${90}^o$

Answer 1

The correct option is A $2\times {\sin }^{-1}\frac{1}{\sqrt{6}}$

Hence, the option $A$ is the correct answer.
