Find angular magnification

    1. The problem statement, all variables and given/known data

    The wing of an insect is 1.7 mm long. When viewed through a microscope, the image is 1.4 m long and is located 5.9 m away. Determine the angular magnification.

    2. Relevant equations
    di/do=hi/ho
    M=beta/alpha

    alpha=object size/object distance

    beta=image size/image distance
    3. The attempt at a solution
    di/do=hi/ho
    5.9/do=1.4/0.0017
    do=0.00716

    alpha=0.0017/0.00716=0.237

    beta=1.4/5.9=0.237
    M=1
    This answer is wrong. Can anyone please point out the mistake.

    Which kind of microscope is being used, and in what mode?

    This is all the information that I have. I did all the calculations using simple microscope equations.
