Three prisms of crown glass, each have angle of prism `9^(@)` and two prisms of flint glass are used to make direct vision spectroscope. What will be the angle of flint glass prisms if `mu` for flint is `1.69` and `mu` for crown glass is `1.53` ?

A prism of crown glass with refracting angle of 5^(@) and mean refractive index = 1.151 is combined with a flint glass prism of refractive index = 1.65 to produce deviation. Find the angle of fliint glass.

A prism of crown glass with refracting angle of 5^(@) and mean refractive index = 1.151 is combined with a flint glass prism of refractive index = 1.65 to produce deviation. Find the angle of fliint glass.

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 ?

A combination of two prisms, one of flint and other of crown glass produces dispersion without deviation. The angle of flint glass prism is 15^@ . Calculate the angle of crown glass prism and angular separation of red and violet rays on emergence 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 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?

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 ?

A prism of crown glass having angle of refractive as 3^(@) and refractive index = 1.51 is combined with one flint glass prism of refractive index = 1.65 to produce dispersion without deviation. Find the angle of flint glass and net dispersion. Given, mu_(v) = 1.523, mu_(R) = 1.513 (for crown glass) mu'_(v) = 1.665, mu'_(R) = 1.645 (for flint glass)
