what is the focal length of a plane mirror?
moparvej3943gmailcom:
the focal length can be said to be the
lens of a sphere of infinite radius
so its focal length will also be half of infinite
that means infinite

HI FRIEND....
Mathematically, a plane mirror can be considered to be the limit of either a concave or a convex spherical curvedmirror as the radius, and therefore thefocal length, becomes infinite.
I HOPE I HELPED YOU....
PLEASE MARK IT AS BRAINLIST IF IT'S HELPFUL...

Answer:
Explanation:
Focal length = f = R/2
R - Radius of curvature of mirror
f = infinite(symbol) / 2
= Infinite
