Why are the mirrors fitted on the outside of cars convex?
Advertisements
उत्तर
- The image formed by a convex mirror is small and straight.
- This image remains straightforward; But as we move the mirror further away from the object, the image becomes smaller.
- As a result, we see all the surrounding images in the mirror.
- The use of convex mirrors in the outside of the vehicle gives the driver a straight, narrow and clear image of the vehicles behind the vehicle.
- Therefore, the mirror fitted on the outside of the vehicle is convex.
