Two identical prisms $ABC$ and $A\text{'}B\text{'}C\text{'}$ are given. Which of their following placement will yield maximum dispersion:

A prism $\mathrm{ABC}$ (with $\mathrm{BC}$ as base) is placed in different orientations. A narrow beam of white light is incident on the prism as shown in the figure ahead. In which of the following cases, after dispersion, the third colour from the top corresponds to the colour of the sky :

The angle of deviation through a prism is maximum when the angle of incidence is:

In the following figure, the angle of refraction is

In the figure shown the refracted ray is

The correct relation related to glass prism is:

The light that consists of many wavelengths or many colours is called:
