Convex mirror A convex mirror is a curved mirror in which the reflecting surface bulges towards the light source. Convex mirrors reflect light outwards; therefore, they are not used to focus light. A convex mirror is also known as a fish eye mirror or diverging mirror.

Images formed by convex mirrors cannot be projected on a screen since the image is inside the mirror. Therefore, its focal length cannot be determined directly. The image is smaller than the object but gets larger as the object approaches the mirror. The ray diagram of a convex mirror is shown below.

Rules to draw a ray diagram in the convex mirror
A ray parallel to the principal axis, after reflection, appears to diverge from the principal focus in a convex mirror.

Physics Practical Class

A ray passing through the principal focus of a concave mirror or a ray which is directed towards the principal focus of a convex mirror, after reflection, will emerge parallel to the principal axis.

Physics Practical Class

A ray directed in the direction of the centre of curvature of a convex mirror, after reflection, is reflected along the same path.

Physics Practical Class

A ray incident obliquely to the principal axis, towards a point P (pole of the mirror), a convex mirror is reflected obliquely. The incident and reflected rays follow the laws of reflection at the point of incidence (point P), making equal angles with the principal axis.
