Concave and convex meaning: Smooth, polished, or gleaming surfaces are called mirrors. They produce images by reflecting the light beam. Plane and spherical mirrors are the two types of mirrors. Spherical mirrors are further divided into convex and concave mirrors. To grasp the difference between a concave and a convex mirror, it is necessary to first understand what they are. Convex mirrors have an outwardly bulging reflecting surface, and concave mirrors have an inwardly bulging reflecting surface. The image that forms in these two mirrors is the most significant distinction. To put it another way, convex mirrors create smaller pictures whereas concave mirrors create larger ones.
A mirror with a curved reflecting surface is known as a curved mirror. Convex (bulging outward) or concave (bulging inward) surfaces are possible (recessed inward). The surfaces of most curved mirrors are formed like a section of a sphere; however different shapes are occasionally utilized in optical equipment.
Concave mirror: Concave mirrors are those with an inward curve in the centre that reflects light inward to focus it on a single focal point. Depending on the distance between the mirror and the object, concave mirrors produce several forms of pictures.
Convex mirror: Convex mirrors are those with an outward bulge in the center that allows light from the item to fall directly on it. This is a reference to the fact that when parallel rays strike the reflective surface of a convex mirror, the beams diverge.
Concave mirrors are commonly used as makeup mirrors, telescopes, automotive headlights, torches, and dental clinic mirrors because they produce a larger picture than the real size of the object. Convex mirrors, on the other hand, produce decreased images and are therefore mostly employed in rearview mirrors, sunglasses, and other similar applications.

The difference between concave mirror and convex mirror is listed below in the tabular form:
|Comparison||Concave mirror||Convex mirror|
|Appearance||A concave mirror is created when the outer surface of a spherical mirror is painted.||A convex mirror has the inside surface of a spherical mirror painted.|
|Also called||Converging mirror||Diverging mirror|
|Design||A concave mirror is either spherical or hollowed out. Concave refers to the shape of a circle's inside.||A convex mirror is a curved, round mirror. Convex refers to the shape of a circle's outside.|
|Reflecting surface||Here, only the inner surface reflexes.||Here, only the outer surface reflexes.|
|Focal length||The focal length is negative||The focal length is positive.|
|Nature of image||Real and virtual.||Only virtual.|
|Use||They give a magnified image of the objects and are used in reflecting telescopes, shaving mirrors, torch lights, and other similar devices.||Convex mirrors are utilized in vehicles as a side or rearview mirror because they cover a larger region of vision.|
The above table shows distinguish between concave and convex mirror or concave and convex mirror difference.
