Glass Prism

A student is performing an experiment with two triangular glass prisms. He places the first glass prism on its base. The second glass prism is placed upside down behind the first glass prism. When a beam of white light is allowed to fall on the first glass prism, then a patch of ordinary white light is obtained on a screen placed behind the second glass prism. (a) Draw a ray diagram to show the above· arrangement of two glass prisms and the light passing through them. (b) What is the function-of (i) first prism, and (ii) second prism, in this arrangement?

A crown glass prism and a flint glass prism are combined to produce dispersion without deviation. Mean refractive indices of crown , and flint glass are respectively 1.5 and 1.6. Ratio of angle of crown glass prism to that of flint prism is

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 ?

Flint glass prism is joined by a crown glass prism to produce dispersion without deviation. The refractive indices of these for mean rays are 1.602 and 1.500 respectively. Angle of prism of flint prism is 10^(@) , then the angle of prism for crown prism will be

A flint glass prism and a crown glass prism are to be combined in such a way that the deviation of the mean ray is zero. The refractive index of flint and crown glasses for the mean ray are 1.6 and 1.9 respectively. If the refracting angle of the flint prism is 6^@ , what would be the refracting angle of crown prism?

The dispersive powers of flint glass and crown glass are 0.053 and 0.034 respectively and their mean refractive indices are 1.68 and 1.53 for white light .Calculate the angle of the flint glass prism required to form an achromatic combination with a crown glass prism of refracting anlge 4^@ .

Find the angle of flint glass prism which produces the same angular dispersion for c and F wavelengths in 10^(@) crown glass prism. For crown glass : mu_(F) = 1.5230, mu_( c) = 1.5145 For flint glass : mu'_(F) = 1.6637, mu'_( c) = 1.6444 .
