What type of mirror is known as a converging mirror?

A concave mirror is known as a converging mirror because it has a reflective surface that curves inward, resembling a portion of a sphere. When parallel rays of light strike the surface of a concave mirror, they are reflected inward and converge to a point known as the focal point. This property is utilized in various applications, such as in shaving mirrors or satellite dishes, where it is beneficial to focus light or signals.

In contrast, flat mirrors, also known as plane mirrors, reflect light in a predictable manner without converging or diverging the rays. Convex mirrors, which curve outward, reflect light rays outward and are used primarily in situations where a wider field of view is needed, such as in security mirrors or vehicle side mirrors. The other types do not exhibit the converging properties that define a concave mirror.
