A simple magnifier makes an image appear at the near point distance from the eye of the viewer (25 cm).What is the magnifying power of the magnifier if it is constructed of a lens of focal length of 5.0 cm?
A)1.2
B)5.0
C)6.0
D)63

Question

Quizplus · Accepted Answer

The magnifying power of a simple magnifier is given by:
Magnifying power = 1 + (25 cm / f)
where f is the focal length of the lens.

Substituting the given values, we get:
Magnifying power = 1 + (25 cm / 5.0 cm) = 6.0

Therefore, the magnifying power of the magnifier is 6.0. Therefore, the correct choice is C.
