Problem 3
A transverse object of height is placed before a converging thin lens of focal length , perpendicular to its principal axis. Its distance from the lens is ; use the convention that image distance lies opposite the object and signed transverse magnification is . (a) Use the principal-ray construction to determine the image character and location. (b) Find the signed magnification and image height. (c) If a smaller object is placed at the same position, state what changes and what does not, explaining with the lens equation.

Magnification is the ratio of image to object height. The negative sign records that an object above the axis forms an image below it.
