A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of incidence is the angle between the incident ray and the surface normal ,if we go to see in a plane mirror the image is congruent to the object
thus its focal length is infinity
thus its focal length is infinity
