Determine the angle of flint glass prism,which should be combined with a crown glass prism of `5^@` so as to give dispersion but no deviation.
Given,for crown glass:`mu_v=1.523,mu_r=1.515,` for flint glass:`mu_v=1.688,mu_r=1.650`.

A crown glass prism of refracting angle 6^@ is to be achromatised for red and blue light using a flint glass prism.Find the angle of the second prism ang also the mean deiation from the following data: Refractive index for crown glass : mu_r=1.520,mu_b=1.531 Refractive index for flint glass: mu_r = 1.662 , mu_b = 1.684 .

A combination of two prisms,one of flint and other of crown glass produces dispersion without deviation.The angle off teh flint glass prism is 15^@ .Calculate teh angle of crown glass prism and the angular separation of the red and violet rays on emregence from the spectroscope .( mu for crown glass = 1.52, mu for flint glass=1.65 , omega for crown glass 0.02 , omega for flint glass =0.03).

The refractive indices of the crown glass for blue and red light are 1.51 and 1.49 respectively and those of the flint glass are 1.77 and 1.73 respectively.An isosceles prism of angle 6^@ is made of crown glass.A beam of white light is incident at a small angle on this prism .The other flint glass isosceles prism is combined with the crown glass prism such that there is no deviation of teh incident light.Determine the angle of the flint glass prism.Calculate the net dispersion of the combined system.

How does the angle of minimum deviation of a glass prism of refractive index 1.5 change,if it is immersed in a liquid of refrctive index 1.3?

A thin prism of angle 15^@ made of glass of refractive index = 1.5 is combined with another prism of glass of refractive index = 1.75 .The combination of prism produces dispersion without deviation.The angle of the second prism should be
