Question

The spherical aberration can be minimized by

• A. reducing the aperture of the lens
• B. using specially made meniscus lens
• C. combination of lenses made of different glasses
• D. all the above

Answer 1

The correct option is D

all the above

Explanation

Spherical aberration- Spherical aberration is an optical phenomenon that happens when light rays strike a lens or a mirror at its edge, as opposed to those that strike the center.

1. It denotes a gadget that deviates from the norm, resulting in an imperfection in the image produced.
2. It can be corrected by reducing the aperture of the lens, using a specially made meniscus lens, and by using a combination of lenses made of different
   glasses.

Hence, the correct answer is option (D).
