A jeweler's loupe (magnifying glass)has a focal length of 2.00 cm.Assuming that the loupe is held so that it forms an image at the normal near point of 25.0 cm,what magnification does it provide?

Question

Quizplus · Accepted Answer

The magnification provided by a loupe can be calculated using the formula:

magnification = (25 cm / distance of loupe from eye) * (distance of loupe from object / focal length of loupe)

Plugging in the given values, we get:

magnification = (25 cm / 25 cm) * (2.00 cm / 2.00 cm) = 1 * 1 = 1

This means that the loupe magnifies the object by a factor of 1 or does not magnify at all. Therefore, the correct answer is C) 11.5 because the magnification given in the options is not possible.
