A thin prism of angle 15^@ made of glass of refractive index mu_1=1.5 is combined with another prism of glass of refractive index mu_2=1.75 . The combination of the prisms produces dispersion without deviation. The angle of the second prism should be

The refractive indices of crown glass for blue and red light are 1.523 and 1.513, respectively and of dense flint glass, 1.773 and 1.743, respectively. Calculate the dispersive power of the material. What must be the anlgle of a flint glass prism which may be combined with a crown glass prism of angle 5^(@) so that the combination produces dispersion without deviation? What dispersion does the combination produces?

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)
