A person uses a convex lens of focal length 5.0 cm as a magnifying glass.What is the angular magnification if the person's eye is relaxed and has a near point of 25 cm?

Question

Quizplus · Accepted Answer

The formula for angular magnification is given by:

magnification = (1 + (25/f))/2

where f is the focal length of the lens.

Substituting f = 5.0 cm in the above formula, we get:

magnification = (1 + (25/5.0))/2 = 5.0

Therefore, the angular magnification is 5.0.

Hence, the correct answer is choice B.
