determine the image distance for an object that is 45.0 cm from a double convex lens having a focal length of 15.0 cm

  • Physics -

    Let the image distance be Di

    1/45 + 1/Di = 1/15

    1/Di = 2/45

    Di = 22.5 cm

    You do not need to know that the lens is double convex. All you need is the focal length.
