On which factors does the angle of deviation produced by a prism depend?

For a prism with a prism angle of $60^\circ$ and a refractive index of $\mu = \sqrt{2}$,the angle of minimum deviation is .......... $^\circ$.

$A$ ray of light is incident on a $60^{\circ}$ prism at the minimum deviation position. The angle of refraction at the first face (i.e.,incident face) of the prism is.......$^{\circ}$

Three glass prisms $A, B$ and $C$ of the same refractive index are placed in contact with each other as shown in the figure,with no air gap between the prisms. $A$ monochromatic ray of light $OP$ passes through the prism assembly and emerges as $QR$. The conditions of minimum deviation are satisfied in which prisms?

By placing the prism in the minimum deviation position,the images of the spectrum:

$A$ prism is made up of material of refractive index $\sqrt{3}$. The angle of the prism is $A$. If the angle of minimum deviation is equal to the angle of the prism,then the value of $A$ is: (in $^{\circ}$)
