Difference Between Concave and Convex Mirrors

Concave and convex mirrors are two types of curved mirrors that have distinctly different characteristics and uses. Here are the key differences between the two:

Concave Mirror

A concave mirror is a mirror with a reflecting surface that curves inwards. It is also known as a converging mirror because it converges light rays to a focal point. Concave mirrors can form both real and virtual images, depending on the object distance and position. Real images are formed in front of the mirror, while virtual images are formed behind the mirror. Concave mirrors are used in applications such as shaving mirrors, solar concentrators, and headlights.

Convex Mirror

A convex mirror is a mirror with a reflecting surface that curves outwards. It is also known as a diverging mirror because it diverges light rays. Convex mirrors always form virtual images that are smaller and upright. These mirrors have a wider field of view compared to concave mirrors, making them suitable for use as side-view mirrors in vehicles, security mirrors in stores, and decorative mirrors.

In summary, concave mirrors converge light rays and can form both real and virtual images, while convex mirrors diverge light rays and always form virtual images. The choice of mirror depends on the specific application and the desired image characteristics.
