The prism is an equilateral prism so all of its angles will be . The picture shows a ray of monochromatic light passing through a glass prism surrounded by air. When the incident falls on the surface of the prism, it gets refracted towards the normal. When the refracted ray goes towards the other surface (on right side), it gets refracted away from the normal. \nDraw two normals, one on the left face of the prism and other on the right face of the prism. \nFrom the figure we can write-
\n\n\n\n\n\n
Apply Snell’s Law for first refraction which is as follows:
\n\n
\nWhere = refractive index of first material \n= refractive index of second material
\n\n
=angle of incidence. \n=angle of refraction. \nApplying snell's law at the both surfaces,
\n\n\n\n
We have the value of from the geometrical calculations –

For a prism the angle of prism is equal to angle of minimum deviation and refractive index of its material is . Then the angle of minimum deviation will be
Light is incident normally on the short face of a prism. A liquid is poured on the hypotenuse of the prism. If the refractive index of the prism is , find the maximum refractive index of the liquid so that light is totally reflected
In the figure is the cross-section of a right angled prism and is the cross-section of a glass slab. The value of $\theta$. So that light incident normally on the face does not cross the face is (given )
