HW problem help?

  1. Apr 15, 2008 #1
    A child holds a candy bar 10.0cm in front of a convex mirror and notices that the image is only one-half the size of the candy bar. What is the radius of curvature of the mirror?

    Welcome to PF kdl8614,

    What have you attempted thus far?

    P.S. We have homework forums for such questions.

    No problem, it'll get there eventually.

    With respect to the question, you must have some idea. What are the concepts involved? Have you read your class notes?
