The refractive indiceis of crown and flint glasses for blue and red rays are 1.523 ,1.513 adn 1.773,1.743 rspectively.Calculate the dispersive powers of teh two glasses.

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.

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?

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 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'.

Refractive index of glass is 1.5 find critical angle for glass.

The dispersive pwoers of crown and flint glasses are 0.03 and 0.05 respectively.If difference in the refrative indices for blue and red colour is 0.015 for crown glass and 0.022 for flint glass,calculate the angles of the two prisms for a deviation of 2^@ without dispersion.

Two monochromatic rays of light are incident normally on the face AB of an isosceles right-angled prism ABC.The refractive indices of the glass prism for the two rays 1 and 2 are respectively 1.35 and 1.45[Fig.2.76]Trace the path of these rays after entering through the prism .

A beam of light consisting of red, green and blue and is incident on a right angled prism. The refractive index of the material of the prism for the above red, green and blue wavelengths are 1.39, 1.44 and 1.47 respectively. The prism will : .

What is the critical anle for a ray going from glass into water?The refractive indices of glass and water are 1.62 and 1.32 respectivley.
