The angle of a crown glass prism of refractive index 1.52 is `6^(@)` . What should be the angle of a flint glass prism of refractive index `1.65` , so that the two prisms produce a direct vision prism ?

In a direct vision spectrograph , there are 3 crown glass prisms and 2 flint glass prisms , each of refracting angle 24^(@) . What should be the angle of the crown glass prism , if the refractive index of crown glass for mean colour is 1.52 and that of flint-glass of 1.65 ?

The angle of crown glass (mu=1.52) prism is 5^(@) .What should be angle flint glass (mu=1.63) .Prism ,so that the two prism may be used in direct vision spectroscope?

A thin glass prism of angle 6^(@) of refractive index 1.5 is combined with another glass prism of refractive index 1.6 to produce dispersion without deviation. What is the angle of the second prism ?
