What is a convex mirror primarily used for?

A convex mirror is primarily used to create virtual images that appear smaller than the actual object. This characteristic makes convex mirrors particularly useful in situations where a wider field of view is necessary. For example, they are commonly employed in vehicle side mirrors and security mirrors because they allow drivers or security personnel to see a broader area than would be visible with a flat or concave mirror. The virtual images produced by convex mirrors seem to be located behind the mirror, and they provide a view of a larger area, albeit at a reduced size.

Additionally, the images formed by convex mirrors are upright, providing practical benefits for navigation and surveillance. However, instead of presenting real images, which can be projected onto a screen, convex mirrors create virtual images that cannot be captured on a traditional display. This unique property identifies them as an essential tool in various applications that benefit from a wide viewing angle while maintaining image orientation.
