Only the reflected rays making a small angle with the mirror, meet at a point when produced backward
Light of different colours make different images

2. In image formation from spherical mirrors, only paraxial rays are considered because they

Are easy to handle geometrically
Contain most of the intensity of the incident light
Form nearly a point image of a point source
Show minimum dispersion effect
