Two uses of concave convex and plane mirror

Dear student,
Concave mirror- 
1. headlights of cars 
2. dentist's mirror 
3. solar devices 
4. reflecting telescopes 
5. satellite dishes 
6. personal uses(men shaving, women applying make-ups etc) 
7. reflectors in flash-lights 8. electron microscopes 
Convex mirror- 
  1. Rear-view mirrors of vehicles

  2. Safety mirrors in stores

  3. It is used as a reflector in street lamps so as to diverge light over a large area

  4. They are usually mounted on a wall or ceiling where hallways intersect each other, or where they make sharp turns.

Plane mirror- 

1. Plane mirrors are used as looking glass


2. Plane mirrors also have many scientific uses. In most of the measuring instruments, a plane mirror is placed under the scale and pointer. When the pointer moves, the image in the plane mirror also moves. Now the eye is so placed that the pointer covers its own image, and thus the pointer and its image coincides. Thus the eye, the pointer and its image in the mirror are in the same line perpendicular to the scale. This helps in getting the correct reading.

3. Plane mirrors are also used in constructing periscope which is used in submarines.

4. Plane mirrors are used in solar cookers.

5. Plane mirrors are used to make the kaleidoscope,a toy which produces beautiful patterns from colored paper, pieces of glass or small colored beads.
