How does a magnifying glass make an object look bigger and closer?

Question:

How does a magnifying glass work to make an object appear bigger and closer?

Answer:

A magnifying glass works by using a converging lens with a small focal length, typically several centimeters. When an object is placed in front of the magnifying glass between the lens and the focus, it appears larger and closer to the viewer.

Explanation:

Converging lens: The magnifying glass consists of a single converging lens with a small focal length, allowing it to converge light rays and create an enlarged image of the observed object.

Object placement: In order to see the magnified image, the observed object must be positioned between the magnifying glass and its focus, closer to the focus point. This placement allows the viewer to see an upright and enlarged figure of the object.

Focusing: By adjusting the distance between the magnifying glass and the observed object, the viewer can focus and sharpen the image. This process of adjusting the magnifier enables the viewer to see the object more clearly and in greater detail.

Visual perception: The magnifying glass enhances the visual perception of the object by enlarging it and bringing it closer to the viewer. This magnification effect is particularly helpful for individuals with normal eyesight, with an optimal viewing distance of around 25 cm for clear vision.
