Uses of concave and convex lenses

Answer 1

Dear student,

USES OF CONCAVE MIRROR
1. It is used in torches, search lights, and vehicle headlights to get powerful parallel beam of light.
2. It is used as a shaving mirror to see a larger image of the face.
3. It is used by dentists to see a larger image of the teeth of the patients.
4. It is used to concentrate sunlight to produce heat in solar furnaces.

USES OF CONVEX MIRROR
1.They are commonly used as rear-view mirrors in vehicles because it enables the driver to see the traffic behind him/her by giving an erect and diminished image. Thus they give driver a wider field view of the area under traffic which is not possible by plane mirrors.
2. They are also used in magnifying glasses.
3. They can be used street light reflectors because they can spread light over bigger area.

Thanks and regards.
