If the angle of minimum deviation produced by an equilateral prism is equal to the angle of the prism,then the refractive index of the material of the prism is nearly

$A$ light ray is incident upon a prism in minimum deviation position and suffers a deviation of $34^o$. If the shaded half of the prism is removed,the ray will

$A$ light ray is incident on a prism of angle $A = 60^{\circ}$ and refractive index $\mu = \sqrt{2}$. The angle of incidence at which the emergent ray grazes the surface is given by:

$A$ combination of two prisms,one of flint glass and the other of crown glass,produces dispersion without deviation. The angle of the flint glass prism is $15^\circ$. The net angular dispersion for red and violet light will be ..... (Given: for crown glass $\mu = 1.52, \omega = 0.02$; for flint glass $\mu = 1.65, \omega = 0.03$). (in $^\circ$)

$A$ graph is plotted between angle of deviation $(\delta)$ and angle of incidence $(i)$ for a prism. The nearly correct graph is

Explain the minimum deviation angle for a prism using the graph of deviation angle versus incidence angle.
