$A$ thin prism of angle $5^{\circ}$ is placed at a distance of $10\,cm$ from an object. What is the distance of the image from the object? (Given refractive index $\mu$ of prism $= 1.5$)

From the graph of angle of deviation $\delta$ versus angle of incidence $i$ for an equilateral prism, the refractive index of the material of the prism is:

$A$ prism of a certain angle deviates the red and blue rays by $8^{\circ}$ and $12^{\circ}$ respectively. Another prism of the same angle deviates the red and blue rays by $10^{\circ}$ and $14^{\circ}$ respectively. The prisms are small-angled and made of different materials. The dispersive powers of the materials of the prisms are in the ratio:

$A$ light ray incident normally on one face of an equilateral prism and emerges out grazingly at the other face. The refractive index of the prism is

An achromatic prism is made by combining two prisms $P_1$ $(\mu_v = 1.523, \mu_r = 1.515)$ and $P_2$ $(\mu'_v = 1.666, \mu'_r = 1.650)$,where $\mu$ represents the refractive index. If the angle of the prism $P_1$ is $10^o$,then the angle of the prism $P_2$ will be.....$^o$

Consider two equivalent,triangular hollow prisms $A$ and $B$ made of thin glass plates and arranged with negligible spacing as shown in the figure. $A$ beam of white light is incident on prism $A$ from the left. Given that the refractive index of water is inversely related to temperature,the beam to the right of prism $B$ would not appear white,if
