Solution
The kinds of SPHERICAL MIRRORS are :
- CONCAVE MIRROR
- CONVEX MIRROR
CONCAVE MIRROR: Silvered surface is away from the centre of curvature and focal length is negative, i.e. reflecting surface is towards the centre of curvature.
CONVEX MIRROR: Silvered surface is towards the centre of curvature and focal length is positive i.e. reflecting surface is away from the centre of curvature. It always forms diminished (small) image which is VIRTUAL.
