In an isosceles prism of prism angle 45^(@) , it is found that when the angle of incidence is same as the prism angle, the emergent ray grazes the emergent surface. Find the refractive index of the material of the prism.For what angle of incidence the angle of deviation will be minimum ?

(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 .

In a condition of minimum deviation mu = sqrt(3) . Angle of incidence = 2 x angle of refraction then find angle of prism.

A ray of light is incident on a prism ABC of mu = sqrt(3) as shown in Fig. Find the angle of incidence for which the deviation of light by the prism ABC is minimum. By what angle should the second prism be rotated so that final ray suffers net minimum deviation ?
