For a prism of refractive index $1.732$,the angle of minimum deviation is equal to the angle of the prism. The angle of the prism is......$^o$

$A$ 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 along the same path due to reflection at the silvered surface. The refractive index of the material of the prism is:

Minimum deviation is observed with a prism having angle of prism $A$,angle of deviation $\delta$,angle of incidence $i$,and angle of emergence $e$. We then have generally

In a thin prism of glass (refractive index $\mu = 1.5$),which of the following relations between the angle of minimum deviation $\delta_m$ and the angle of the prism $A$ (where $A = 2r$ for a thin prism) is correct?

$A$ thin prism of angle $6^{\circ}$ made of glass of refractive index $1.5$ is combined with another prism made of glass of refractive index $1.75$ to produce dispersion without deviation. Then the angle of the second prism is ...... (in $^{\circ}$)

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