$<marquee direction= "left"> This is because mirror performs reflection and lens refraction. Mirror sends the light ray back, so it has one principal focus while lens, having to bend the light ray lets the light ray pass through the second principal focus to form an image.$

Bez the mirror is the part of single sphere
While the lens is the part of junction of two spheres
So each sphere has one focus
In case of lens it becomes two and in case of mirror it remain as one only.
