You are given prisms made of crown glass and flint glass with a wide variety of angles. Suggest a combination of prsims which will- disperse (and displace) a pencil of white light without much deviation.

You are given prisms made of crown glass and flint glass with a wide variety of angles. Suggest a combination of prisms which will- deviate a pencil of white light without much dispersion.

Out of crown and flint glasses, which has the larger value of dispersive power?

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.

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

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 dispersive pwoers of crown and flint glasses are 0.03 and 0.05 respectively.If difference in the refrative indices for blue and red colour is 0.015 for crown glass and 0.022 for flint glass,calculate the angles of the two prisms for a deviation of 2^@ without dispersion.

In dispersion of light through a glass prism angle of deviation is minimum for:

How does the angle of minimum deviation of a glass prism vary, if the incident violet light is replaced by red light? Give reason.

When a ray of light passes through a glass prism then a spectrum is obtained on the screen Which colour of the spectrum suffers most deviation and which colour the least deviation?
