A real image of a distant object is formed by a plano-convex lens of its principal axis. Spherical aberration

A

absent

B

smaller, if the curved surface of the lens face the object.

C

smaller, if the plane surface of the lens faces the object.

D

same, which ever side of the lens faces the object.

Text Solution

Verified by Experts

The correct Answer is:
B
When the curved surface of the lens faces the object, the spheical aberration is smaller. The total deviation is shared between the curved and the plane surfaces.
