B Centre of curvature of a mirror and the perpendicular

  1. May 10, 2017 #1
    If the normal is always 90 to the mirror can we assume that it always passes through centre of curvature?
    The light rays passing through the centre are reflected back in the same direction as angle of incidence is 0
    and incident angle is 90
    so, the normal should pass through the centre.

    If the mirror is spherical it will pass through centre
