USES OF SPHERICAL MIRRORS
1. For heating purpose: They are used for converging solar radiations in solar cookers to generate adequate heat for cooking purposes.
2. As reflectors: They are used as reflectors in projectors, lighthouse headlights, searchlights, torches, etc. to obtain a parallel beam of light. This is possible when the source of light (ie the bulb) is placed at the focus of the concave mirror which acts as a reflector Large concave mirrors are used in reflecting telescopes.
3. As shaving mirrors: Concave mirrors are used as shaving mirrors and as make-up mirrors to see the enlarged, erect image of the face (for this to happen, the face must be placed close to the mirror, Le within the focal point of the mirror)
4.As doctor's head mirror: Concave mirrors are used by doctors to focus light on the internal body parts such as teeth, ear, nose and throat. This is possible if a parallel beam of light is incident on a concave mirror which focusses the beam to a point. In this case, the beam is converged to the internal body part to be examined.
5. In floodlights: In a floodlight, a bright bulb is positioned between F and P of a concave mirror to obtain a divergent beam.
6. As rear view mirrors: Convex mirrors are used as rear-view mirrors in vehicles like cars, trucks and buses to see the traffic at the back.
7. Vigilance mirrors: Convex mirrors are used as vigilance mirror in shops and departmental stores as anti shoplifting devices.
8.Street lighting: street lights also use Convex mirrors to diverge light over an extended area.
