25.6 Exercise 3

A student wishes to predict the magnification of an image given the distance from the object to a converging lens with an unknown index of refraction. What data must the student collect in order to make such a prediction for any object distance?

1. A specific object distance and the image distance associated with that object distance.
2. A specific image distance and a determination of whether the image formed is upright or inverted.
3. The diameter and index of refraction of the lens.
4. The radius of curvature of each side of the lens.
