Question

Why concave mirrors are used as shaving mirrors?

Answer 1

1. A concave mirror is used as a shaving mirror.
2. It is because when the face is placed near a concave mirror (so that the face is within its focus), a magnified and erect image of the face is obtained.
3. Since the image formed by the concave mirror is magnified and very clear, it is easy to make a smooth save.
4. A person can see all detail easily and shave without any difficulties.

Hence, concave mirrors are used as shaving mirrors.
