$A$ prism of angle $A=1^{\circ}$ has a refractive index $\mu=1.5$. $A$ good estimate for the minimum angle of deviation (in degrees) is close to $N/10$. The value of $N$ is......

Obtain the relation between incidence angle,emergence angle,prism angle,and deviation angle for refraction through a prism.

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

Two beams of red and violet colours are made to pass separately through a prism of $A=60^{\circ}$. In the minimum deviation position,the angle of refraction inside the prism will be

Under minimum deviation condition in a prism,if a ray is incident at an angle $30^o$,the angle between the emergent ray and the second refracting surface of the prism is......$^o$

The angle of minimum deviation produced by a thin prism in air is $\delta_1$. What will be the minimum deviation $(\delta_2)$ if the prism is immersed in liquid? Given: refractive index of glass with respect to air $^a n_g = \frac{3}{2}$ and refractive index of liquid with respect to air $^a n_l = \frac{4}{3}$.
