Asked by fida_147(student) , on 2/10/10


The importance of convex and concave mirror can be given in the following points -

  • Concave mirrors are commonly used in torches, search-lights and vehicles headlights to get powerful parallel beams of light.
  • They are often used as shaving mirrors to see a larger image of the face.
  • The dentists use shaving mirrors to see large images of the teeth of patients.
  • Large concave mirrors are used to concentrate sunlight to produce heat in solar furnaces.

2. For the case of Convex Mirror

  • Convex mirrors arecommonly used as rear-view (wing) mirrors in vehicles. These mirrors are fitted on the sides of the vehicle, enabling the driver to see traffic behind him/her tofacilitate safe driving.
  • Convex mirrors are preferred because they always give an erect, though diminished,image. Thus convex mirrors enable the driver to view much larger area than would be possible with aplane mirror.
