Answer in Brief
Give scientific reason.
Simple microscope is used for watch repairs.
- A magnification of about 20 times is obtained by a simple microscope.
- When an object is placed within the focal length of a convex lens, one gets a magnified and erect image of the object.
- Thus, the watch repairer can see the minute parts of the watch more clearly with the help of a simple microscope than the naked eye, without any strain on the eye.
Hence, a simple microscope is used for watch repairs.
