A driver uses a convex mirror as a rear view mirror. Explain the reason with the help of a ray diagram.
Answer
A convex mirror diverges the incident light rays and always form a small, erect image between its pole and focus. This enables the driver to use it as a rear view mirror so that he could able to see all the traffic behind him approaching the mirror. It has wider field of view than a plane mirror.
