A prism with a refracting angle of `60^@` gives angles of minimum deviation `53^@,51^@` and `52^@` for blue,red yellow light respectively.What is teh dispersive power of the material of the prism?

On what factors does the dispersive power of the material of a prism depend?

A glass prism is held in water. How is its angle of minimum deviation affected?

A glass prism is held in water. How is its angle of minimum deviation affected?

A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. The angle of minimum deviation is measured to be 40^@ . What is the refractive index of the material of the prism? The refracting angle of the prism is 60^@ . If the prism is placed in water (refractive index 1.33), predict the new angle of minimum deviation of a parallel beam of light.

What is a prism, refracting faces and angle of prism?

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 2^@ 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?

A ray is incident at an angle of incidence i on one surface of a prism of small angle A and emerges normally from the opposite surface. If the refractive index of the material of the prism is mu , the angle of incidence i is nearly equal to

A parallel beam of white ligth falls on a convex lens .Images of blue ,yellow nd red ligth are formed on the other side of the lens at distnaces 20 cm,20.5 cm and 21.4 cm respectively.The dispersive power of the material of the lens is
