The refractive index of a glass is $1.520$ for red light and $1.525$ for blue light. Let $D_1$ and $D_2$ be the angles of minimum deviation for red and blue light,respectively,in a prism of this glass. Then,

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

Draw a diagram of a right-angled prism for which the object and image are of the same size.

$A$ ray of light is incident at an angle of $60^o$ on one face of a prism of angle $30^o$. The ray emerging out of the prism makes an angle of $30^o$ with the incident ray. The emergent ray is

The figures represent three cases of a ray passing through a prism of angle $A$. The case corresponding to minimum deviation is

For a small angled prism with prism angle $A$,the angle of minimum deviation $\delta$ varies with the refractive index $\mu$ of the prism as shown in the graph.
