The angle of minimum deviation for a prism may be calculated from the prism equation. An online calculator can be found here: http://hyperphysics.phy-astr.gsu.edu/Hbase/geoopt/prism.html#c2 The equation can't be typed but a grahic can be found here: http://hyperphysics.phy-astr.gsu.edu/Hbase/geoopt/imggo/prismeq.gif
angle of deviation = angle of prism x ( refractice index -1)
The term angle of deviation is used in reference to a prism.
As the angle of incidence is increased, angle of deviation 'd' decreases and reaches minimum value. If the angle of incidence is further increased, the angle of deviation is increased. Let dm be the angle of minimum deviation. The refracted ray in the prism in that case will be parallel to the base.

The minimum deviation of a prism can be calculated using the formula: δ = (n - 1)A, where δ is the minimum deviation, n is the refractive index of the prism, and A is the angle of the prism. If the refractive index of the prism is three to the power of half, or √3, and the value of A is known, the minimum deviation can be calculated using the formula.
It is named after the type of prism used in the instrument. A constant deviation prism has the property that the angle between light entering the prism (the incident light) and light exiting the prism (the emergent light) is always the same, no matter what the angle of the incident light to the prism.
the smallest angle between the incident and the emergent ray
angle between two edges and angle of incidence how denser the object is
the dispersive power of prism can be defined as the rate of change of angle of deviation in specific spectrum of light ..
f a line is drawn parallel to the angle of incidence axis (X-axis), it cuts the graph at two points, showing that there are two values of angle of incidence for an angle of deviation. However, at the point of angle of minimum deviation, the line will be tangent to the curve showing that for minimum angle of deviation there is only one angle of incidence.
difference between ordinary prism and constant deviation prism
By keeping the prism in minimum deviation position, the RI of the prism can be calculated efficiently.
