Expert Answer
- A ray passing through the centre of curvature is reflected back its own path.
- A ray parallel to the principal axis, after reflection passes through the focus F in case of a concace mirror.
- Similarly, a ray passing through the focus, after reflection, becomes parallel to the principal axis.
- For a ray that is incident on the pole of the mirror, the angle of reflection is equal to the angle of incidence.
