Question:

A physics student uses a converging lens with a focal length of 14 cm to read a small measurement scale.
(a) Maximum magnification is achieved if the image is at (1) the near point, (2) infinity, (3) the far point. Explain.
(b) What are the magnifications when the image is at the near point and infinity, respectively?
