Question

A magnifying glass is a single convex lens with a focal length of ff = 13.0 cm .

What is the angular magnification when this lens forms a (virtual) image at the person's near point (assumed to be 25 cm)?

M =

Answer 1

Answer #1

Angular magnification of magnifying glass is given by:

M = N/f + 1

N = Near point of person = 25 cm

f = focal length of magnifying glass = 13.0 cm

So,

M = (25/13.0) + 1

M = 2.92

Let me know if you've any query.
