what is important in convex & concave mirror
The importance of convex and concave mirror can be given in the following points -
- For the case of Concave Mirror
- 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 are commonly 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 to facilitate 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 a plane mirror.
