| Applications of Spherical Mirrors |
|
 A convex mirror is used as a rear view mirror in vehicles as images are small, erect. This gives us a wider view of the traffic behind. |
| |
|
Convex mirrors are also used in reflecting telescopes. |
| |
|
They are also used as reflectors in street lamps, as a result the light from the lamp diverge over a large area. |
| |
|
A concave mirror is used as a reflector in search light, head light of motor vehicles, telescopes, solar cookers, shaving mirrors. |
| |
|
Concave mirror is used in ophthalmoscope, for reflecting light on to the retina of the eye. |
| |
|
| |
| When an object is kept between two plane mirrors inclined at an angle q, more than one image forms. |
| |
| The total number of images formed in such a case can be related to the angle as follows : |
| |
 |
| |
| Question |
| |
| If q = 90o, find out the number of images formed |
| |
 |
| |
| |
| = 4 - 1 = 3 |
| |
| Three images will be formed. |
