Using the following samples below, elaborate on the practical uses of concave and convex mirrors. Write your answer on a separate sheet of paper.
1. Car rear view mirror
2. Security
3. Street light reflectors
4. Shaving facial hair
5. Car light

Convex mirror is curved in the outward direction and concave mirror in the inward direction.

Explanation:

1. Car rear view mirror: It is a convex mirror which gives the indication of large field of view and it allows the driver to view the traffic behind the car.

2. Security: The reflective bulge surfaces of the convex mirrors reflect the light outwards and provides an expanded field of view of the entire view of shops and other places useful for security.

3. Street light reflectors: They use convex mirrors because they are able to spread the light over the wider area.

4. Shaving facial hair: Concave mirror is used in shaving facial hair. It gives a bigger view of face when it is at the position of pole and focal point of the mirror.

5. Car light: It uses concave mirror because of the converging power it can focus more light rays at a particular point.
