In an experiment for determination of refractive index of glass of a prism by $$i-\delta\ plot$$ it was found that a ray incident at angle $${ 35 }^{ \circ }$$ suffers a deviation of $${ 40 }^{ \circ }$$ and that it emerges at angle $${ 79 }^{ \circ }.$$ In that case which of the following is closest to the maximum possible value of the refractive index?

For the angle of minimum deviation of a prism to be equal to its refracting angle, the prism must be made of a material whose refractive index:

The angle of incidence for a ray of light at a refracting surface of a prism is $${45}^{o}$$. The angle of prism is $${60}^{o}$$. If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are
