Minimum Angle of Deviation for a Prism
At the minimum deviation, Dm the refracted ray inside the prism becomes parallel to its base, i.e. i = e ⇒ r1 = r2 = r, then r = A/2 and Dm = 2i – A, where i is the angle of emergence, r1 and r2 are the angles of refraction and A is the angle of the prism.

What is the prism Snell's law?
As per Snell's law, light travelling from a rarer medium to a denser medium bends towards the normal, and vice versa. Glass is denser than air, and thus, when a ray of light falls on the surface of the prism, it bends towards the normal.

Just fill up your glass dish with water, place the mirror in at an angle, and find a sunny spot to reflect the sunlight through the water. Voila! A water prism! You can make more complicated water prisms by making a trangular tube with plastic, silicon putty, and water – but that is much more involved.
What is meant by Snell's law?
Snell's law is defined as “The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media”.

prism, in optics, a piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light. An ordinary triangular prism can separate white light into its constituent colours, called a spectrum.

What is the type of Prism? The prism is majorly divided into two categories: Regular and irregular. A regular prism has regular polygons as their bases, i.e. the triangular prism will have equilateral triangle bases, a square prism will have square bases. An irregular prism will have irregular polygons as their bases.

What is prism in refraction?
When light passes from air to the glass of the prism, the change in speed causes the light to change direction and bend. Due to the differences in the refraction index between the air and the glass, light bends once entering the prism. Since the sides are angled, the light bends, even more, when it exits the prism.
