USES OF PLANE MIRROR SURFACES
Plane mirrors are frequently used in our daily life. They have a flat surface and produce virtual, upright images. Examples include:
Car rear view mirror;
House and office wall mirror; and
Mirrors lining dance studio walls

1.TELESCOPES
The mirror in the microscope reflects light, enabling us to see things which are too small to be seen with naked eye.
2.MICROSCOPES
A telescope enables us to see distant objects such as the moon and stars clearly. It uses concave reflectors and convex lens as well as plane mirrors.
3.PERISCOPES
A periscope enables us to see objects which are not in direct line of sight. For example, it can be used underwater to see objects above water surface.
4. KALEIDOSCOPE
CONVEX MIRRORS

They have a curved reflecting surface which bulges outwards.
They give a wider scope of view.
They produce images which are:
1. virtual;
2. upright; and
3. diminished.

INTRODUCTION
Mirrors are used a lot in our day to day activities. This presentation shows different types of mirror surfaces and their uses. Some types are:
Plane Mirrors
Convex Mirrors
Concave Mirrors
Characteristics:
Uses:
Convex Mirrors are used in:
Security mirrors
Car wing mirrors
Blind corner mirrors
CONCAVE MIRRORS

They have a curved reflecting surface which caves inwards.
They produce images which are:
1. virtual;
2. upright; and
3. magnified.


Characteristics:
Uses:
Concave Mirrors are used in:
Dentist's mirror
Cosmetic mirror
convex
concave
A kaleidoscope is a tube containing two or more plane mirrors inclined at an angle to each other. Coloured objects are placed at the bottom of the tube so that when the tube is turned different patterns are formed as the coloured objects are reflected by the mirrors.
