Which of the following diagrams correctly shows the dispersion of white light by a prism?

The angle of minimum deviation measured with a prism is $30^o$ and the angle of the prism is $60^o$. The refractive index of the prism material is:

If the angle of a prism is $60^{\circ}$ and the angle of minimum deviation is $40^{\circ}$,then the angle of refraction will be (in $^{\circ}$)

The angle of a prism is $60^o$ and its refractive index is $\sqrt{2}$. The angle of minimum deviation suffered by a ray of light in passing through it is......$^o$

For a symmetric (equilateral) prism,the prism formula can be written as

Monochromatic light passes through a prism. Compared to that in air, inside the prism the light's
