A microscope may be a combination of:

Options

  1. Atwo convex lenses.
  2. Ba convex and a concave lens.
  3. Ctwo concave lenses.
  4. Da convex lens and convex mirror.

Correct answer

A. two convex lenses.

Step-by-step solution

A microscope usually consists of two convex lenses: the objective lens and the eyepiece lens. The objective lens, which is closer to the specimen, produces a magnified real image of the specimen. This image is further magnified by the eyepiece lens, which is positioned closer to the viewer's eye, resulting in a larger virtual image that can be observed.
