CONCAVE MIRROR

             CONCAVE MIRROR

 

             A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point.They are used to focus light.

 

Uses of Concave Mirror

1.   One of the important applications of a concave mirror is in satellite dishes. These antennas are designed to first receive and then amplify (increase) the weaker signals that are sent in space via communication satellites.

 

 

 

 

2.  Another major application of concave mirrors is in headlights of the car. A powerful source of light in a smaller size is placed at the focus point of the concave mirror which is placed at the back of the headlight. Then any light from the focus that will strike the mirror will get reflected in parallel to the axis of the concave mirror. Thus the beam of headlight gets focused in this way.

 

                                   

 

 

 

3. One more application of concave mirrors is in telescopes used for astronomical studies.

 

 

 

 

 

 

4. Shaving mirrors are another example that makes use of concave mirrors because of their curved and reflective surface.

 

 

 



 



5. Dentist and ENT doctors also use concave mirrors in their examinations procedure to obtain a larger image than the original of teeth, ear or skin etc.

 

 

 

6.  Concave mirrors are also used in torches on the same principle as they are used in vehicles headlights.
