Exciting Physics Problem About Lens and Image Formation

Where is the image located when a doctor examines a mole with a magnifying glass?

(a) Where is the image?

Answer:

The image produced by the magnifying glass can be found by applying the lens equation, which involves the focal length and the object distance.

One can find the image produced by the magnifying glass by applying the lens equation, which involves the focal length and the object distance. Calculate according to sign conventions for real (positive) and virtual (negative) images to get the precise image location.

Explanation:

In this physics problem, we are dealing with the concept of lens and image formation. The given data are the focal length of the magnifying glass (17.5 cm), a positive value because the magnifying glass is a converging lens, and the object distance (12.0 cm).

Commonly, lens equations are used to solve this issue. The fundamental lens equation is:

1/f = 1/do + 1/di

Where:

f is the lens focal length

do is the object distance

di is the image distance

By substituting the given data into the lens equation, you will find the image distance di. Remember to consider the sign convention: positive for real images (on the same side as the object) and negative for virtual images (opposite side).
