The focal lengths of a thin convergent lens are 0.5m and 0.484m for red and blue rays, respectively. Find the chromatic aberration and dispersive power of the material of the lens.

The focal lengths of a thin convex lens are 1m and 0.968m for red and blue rays, respectively. Calculate the chromatic aberration and dispersive power of the material of the lens.

Why do thick lenses show more chromatic aberration than thin lenses?

On what factors does the chromatic aberration of a lens depend?

Unit of longitudinal chromatic aberration of a thin lens is __________ .

Can we observe chromatic aberration in the image formed by a plane mirror ?

After cataract operation, a peisun is recommended with concavo-convex spectacles of curvatures 8 cm and 40 cm. Crown glass of refractive indices 1.51 for red and 1.53 for violet colours is used for this. The lateral chromatic aberration occuring due to these glasses is
