$A$ ray of light is incident at an angle of incidence '$i$' on one surface of a thin prism of small angle '$A$'. The ray emerges normally from the opposite surface. If the refractive index of the material of the prism is '$\mu$',the angle of incidence '$i$' is nearly equal to

In an experiment for the determination of the refractive index of glass of a prism by an $i - \delta$ plot,it was found that a ray incident at an angle of $35^o$ suffers a deviation of $40^o$ and emerges at an angle of $79^o$. In that case,which of the following is closest to the maximum possible value of the refractive index?

When light rays are incident on a prism at an angle of $45^o$,the minimum deviation is obtained. If the refractive index of the material of the prism is $\sqrt{2}$,then the angle of the prism will be......$^o$

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:

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

The ratio of the angle of minimum deviation produced by a thin prism $(\mu = 3/2)$ in air to that in a liquid of refractive index $9/7$ is:
