How does angle of deviation vary with the angle of incidence in case of prism ? What is the angle of minimum deviation?

(a) If the refracting angle of a prism is 60^@ and the minimum deviation is 30^@ , then find the angle of incidence. (b) A ray of light passes through an equilateral prism such that the angle of emergence is equal to the angle of incidence and each is equal to 3//4^(th) of the angle of prism. Find the angle of deviation. (c) The refracting of a prism is A and the refractive index of the material of the prism is cotA//2 . Find the angle of deviation. (d) The angle of a prism is 60^@ . What is the angle of incidence for minimum deviation? The refractive index of the material of the prism is sqrt2 .

A beam of monochromatic light is incident at an angle of 55^(@) on one face of an equilateral prism . The angle of deviation is delta and the angle of emergence is 46^(@) . If the angle of minimum deviation (delta_(m)) for the same prism is 45^(@) , then

The relation between angle of incidence i , angle of prism A and angle of minimum deviation for a triangular prism is.

For a prism of refracting angle 60^(@) , it is found that for two angles of incidence 48^(@) and 52^(@) , the angle of deviation is the same . What is the angle of deviation ?

A 60^@ prism has a refractive index of 1.5 . Calculate (a) the angle of incidence for minimum deviation (b) angle of minimum deviation ( c) the angle of emergence of light at maximum deviation (d) angle of maximum deviation.

When an equilateral prism is placed in the position of minimum deviation , the incident ray makes an angle of 37^(@) with the refracting surface . What is the material of the prism , if the angle of 37^(@) with the refracting surface . What is the angle of minimum deviation ?

A certain prism is found to produce a minimum of 38^(@) .It produces a deviation of 44^(@) when the angle of incident is either 42^(@) or 62^(@) .What is the angle of incidence when it is undergoing minimum deviation?
