Answer 1

1) $dentist \: mirror :$

A dentist uses a concave mirror to see the virtual , erect and magnified image of the teeth of patients.

2) $shaving \: mirror :$

Concave mirrors are used for shaving to see a larger image of the face and the fine hairs on it.

3) $rear \: view \: mirrors :$

A convex mirror has a wider field view and it produces a virtual , erect and diminished image of the object. Hence it is used as rear view mirror in vehicles.
