Concave mirror: A concave mirror is a spherical mirror in which the reflection of light takes place at the concave surface, i.e. bent-in surface.

Rules for ray diagram for concave mirror

1) A ray parallel to the principal axis, after reflection, will pass through the principal focus F.

Physics Practical Class

2) A ray passing through the principal focus F of a concave mirror, after reflection, will emerge parallel to the principal axis.

Physics Practical Class

3) A ray passing through the centre of curvature C of a concave mirror, after reflection, is reflected along the same path. The light rays come back along the same path because the incident rays fall on the mirror along the normal to the reflecting surface.

Physics Practical Class

4) A ray incident obliquely to the principal axis, towards a point P (pole of the mirror), on the concave 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.
