In the diagram,a ray is passing through a broken prism. Find the angular deviation for the ray. (in $^{\circ}$)

Yellow light is refracted through a prism producing minimum deviation. If $i_1$ and $i_2$ denote the angle of incidence and emergence for the prism,then ..........

An isosceles prism of angle $120^\circ$ has a refractive index of $1.44$. Two parallel monochromatic rays enter the prism parallel to each other in air as shown. The rays emerging from the opposite faces

$A$ prism has a refracting angle '$A$'. The second refracting surface of the prism is silvered. $A$ light ray falling on the first refracting surface with an angle of incidence '$2A$' reaches the second surface and returns back through the same path due to reflection at the silvered surface. The refractive index of the material of the prism is:

An achromatic prism is made by a crown glass prism $(A_C = 19^o)$ and a flint glass prism $(A_F = 6^o)$. If the refractive indices for violet light are $\mu_{v,C} = 1.5$ and $\mu_{v,F} = 1.66$,then the resultant deviation for the red-coloured ray will be......$^o$

Find the value of the angle of emergence for an emergent ray from the prism in the figure given below. (Refractive index of the material of the prism is $\sqrt{3}$ and the refractive index of air is $1$) (in $^\circ$)
