concave mirror
There are two main types of curved mirrors: concave and convex. Concave mirrors curve inward, causing light rays to converge at a focal point, used in reflecting telescopes and shaving mirrors. Convex mirrors curve outward, causing light rays to diverge, commonly used in security mirrors and side-view mirrors.
-- auto headlights -- front end of a flashlight -- shaving mirror -- satellite TV dish
Concave mirrors are used to focus light, to produce a parallel beam in car headlights, and so you can have a close look while shaving. Convex mirrors are used for making telescopes, viewfinders in vehicles, and used in supermarkets or stores as surveillance as it gives a wider view.
A concave mirror has edges that curve away from the object. Concave mirrors are designed to converge light rays towards a focal point, making them useful for applications such as focusing light in reflecting telescopes or as shaving mirrors.
You can find concave mirrors in museums and microscopes
