Refractive indices of glass for lights of yellow,green and red colours are `mu_y,mu_g` and `mu_r` respectively.Rearrange these symbols in an increasing order of values.

The focal length of a coverging lens is measured for violet,green and red colours.It is f_v,f_g and f_r respectively.We will get

The refractive indices of the crown glass for blue and red light are 1.51 and 1.49 respectively and those of the flint glass are 1.77 and 1.73 respectively.An isosceles prism of angle 6^@ is made of crown glass.A beam of white light is incident at a small angle on this prism .The other flint glass isosceles prism is combined with the crown glass prism such that there is no deviation of teh incident light.Determine the angle of the flint glass prism.Calculate the net dispersion of the combined system.

In Young's double slit experiment, light of green, yellow and orange colours are successively used. Write the fringe widths for the three colours in increasing order.

White light is pased through a glass prism of angle 5^@ .If the refractive indices for red and blue colours are 1.641 adn 1.659 respectively ,calculate the angle of disperson betwen these colours.

Three rays of light -red(R),green(G) and blue(B)-are incident on the face AB of a rigth-angled prism ABC as shown in Fig.3.27. The refractie indices of the material of the prism for red,green and blue wavelengths are 1.39,1.44 adn 1.47 respectively. Trace the path of the rays thruogh the prism.How will the situation change,if these rays were incident normally on one of the faces of an equilateral prism?

Three light rays red, green and blue are incident on a right angled prism 'abc' at face 'ab'. The refractive indices of the material of the prism for red, green and blue wavelengths are 1.39, 1.44 and 1.47 respectively. Out of the three which colour ray will emerge out of face 'ac'? justify your answer. Trace the out of the face 'ac'? Justify your answer. Trace the path of these rays after passing through face 'ab'.

The octahedral complex of a metal ion M^(3+) with four monodentate ligands L_1, L_2, L_3 and L_4 absorbs wavelengths in the region of red, green, yellow and blue, respectively. The increasing order of ligand strength of the four ligands is
