Question

Distinguish between spherical aberration and chromatic aberration and cite a remedy for each

Answer 1

Answer:

The shape of a spherical lens causes a problem called spherical aberration. In spherical aberration, parallel light rays that pass through the central region of the lens focus farther away than light rays that pass through the edges of the lens. The result is many focal points, which produce a blurry image.
