An equiconvex lens of crown glass abd an equiconvex lens of flint glass make an achromatic system.The radius of curvature of convex lens is 0.54 m. If the focal length of the combination for the mean colour is 1.54m and the refractive indices for crown glass are mu_(R)=1.53 and mu_(V)=1.55, find the dispersive power of the flint glass 0.055
In a certain spectrum produced by a glass prism od dispersive power 0.031 , it was found that mu_(r ) = 1.645 and mu_(b) = 1.665 . What si the refractive index for yellow colour ?
A crown glass prism of refracting angle 6^@ is to be used for deviation without dispersion with a flint glass of angle of prism alpha . Given : for crown glass mu_r=1.513 and mu_v = 1.523, for flint glass mu_r=1.645 and mu_v=1.665 . Find alpha
An achromatic converging combination of focal length 60m is formed by placing a convex lens of crown glass and a concave lens of fibt glass in contact with each other. Calculate their focal lengths. If dispersive power of crown glass is 0.03 and that of flint glass is 0.05 .
