plane mirrors have focal length (true or false)

hey!! .
here is your answer =>
the Ray's which bounce upon the plane mirrors never converge, and focus is the point where all the Ray's converge or meet, hence, we can say that plane mirrors doesn't have a focus. and focal length is the distance between the focus and the pole in plane mirrors and optical centre in spherical mirrors. The plane mirrors will have the pole but not the focus. Hence, the plane mirrors doesn't have focal length.
but, the concave and convex mirros do have the focal length. In concave mirrors, the Ray's converge, where as in convex mirror, the Ray's have to drawn back and then, the focus us created.
hope it helps!
