Question

Simple microscope is used for watch repairs​

Answer 1

A simple microscope is a microscope that uses only one lens for magnification. A watch has tiny parts which cannot be seen by our naked eyes. Thus, a simple microscope is used to repair the watches.

 A simple microscope has magnification of about 20 times obtained by the convex lens of small focal length, which is helpful in making the repairer see the parts easily.

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow} {Answer}}$

1. When an object is placed within the focal length of a magnifying glass or simple microscope (convex lens), its larger and erect image is obtained on the same side of the lens as that of the object.

2. By adjusting the distance between the object and the lens,, the image can be obtained at the minimum distance of distinct vision.

3. Thus, a watch repair can see the minute parts of a watch more clearly with the aid of a magnifying glass (a simple microscope) than with the naked eye, without any stress on the eye.

Hence, a simple microscope is used by watch repairs.
