(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A small insect is placed 6.55 cm from a 7.00 cm-focal-length lens. Calculate the position of the image. Calculate the angular magnification.

2. Relevant equations

1/f=1/do+1/di

M=angular magnification=θ'/θ=angle of image/angle of object=N/f where N=near point

3. The attempt at a solution

Finding the image distance is easy using the lens equation and is -101.9 cm. I don't think this problem deals with the near point (although I may be wrong), so the angles need to be known for both the object and image, but I don't know how to do this if the height of the object is unknown. Perhaps I am missing the significance of something (probably something to do with the near point). Thanks for any help.
