Answer:
Specular reflection, also known as regular reflection, is the mirror-like reflection of waves, such as light, from a surface
Explanation:
1.reflection such that the angle of reflection of the light is equal to the angle of incidence and on the opposite side of the normal to the point of incidence.
2.A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence.
3.The image formed by any mirror is located either where the reflected light converges, or where the reflected light appears to diverge from. A spherical mirror is simply a piece cut out of a reflective sphere.
4.A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light. ... The image is smaller than the object, but gets larger as the object approaches the mirror.
5.a line passing through the center of the surface of a lens or spherical mirror and through the centers of curvature of all segments of the lens or mirror
6.These convex mirrors are used for cars because they give an upright image and provide a wider field of view as they are curved outwards.
7.Light rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis after reflecting from the mirror. This point is known as the principal focus of the concave mirror.

9.Concave mirrors are used in search lights and torches so that we have a more focused light beam which will not diverge out and hence help in searching. It is used for different light rays falling on it to a single point.
