Mirror magnification

  1. Nov 17, 2007 #1
    A mirror is required with magnification 9.5 when an object is 14mm from the mirror
    What is the focal length

    My attempt:

    1/f = (1/v)+(1/u)

    Since no object is magnified when the created image is outside of 2f
    this answer can't be correct.

    The answer I get is 15.65.

    2x15.65 is still less than 133
