If the awngle of prism is `60^@` and minimum deviation `38^@`, what is the angle of incidence?

A ray of light is incident on the face o a prism placed in minimum deviation position.If the anle of prism is 60^@ and deviation produced is 34^@ ,find the angle of incidence and refractive index.

Two beams of red and violet colours re mde to pass separaterly through a prism (angle of prism is 60^@ ).In the position of minimum deviation,the angle of refraction will be

A ray of light passing through an equilateral traingular glass prism from air undergoes minimum deviation,when angle of incidence is 3//4 of the angle of prism.Clculate the speed of light in the prism.

A ray strikes the mirror normally, what is the angle of incidence?

The following table gives the value of theangle of minimum deviation for different values of theangle of incidence for a triangular prism. . For what value of the angle of incidence,is the angle of mergence likely to be equal to the angle of incidence?

A ray of light is inclined to one face of the prism at an angle of 50^@ .If the angle of the prism is 60^@ and the ray is deviated through an angle of 42^@ ,lfind the angle which the emergent ray makes with the second face of the prism.

A monochromatic ray of light is made to fall on a normal 60^@ prism under minimum deviation condition.What is the relatin between the angle of incidenc eand the angle of emrgence?

A thin prism of 20^@ angle gives a deviation of 1^@ . What is the value of refractive index of the material of the prism?

A thin prism of 5^@ angle gives a deviation of 3.2^@ .What is the value of refractive index of teh material of the prism?
