Yp Image

YP Image is designed to assist teachers and students when they study image formation by mirrors and thin lenses (geometrical optics). It computes the location and magnification of the image formed by a spherical mirror or a thin lens, and draws a ray diagram on the screen. The diagram may be printed, copied to the clipboard, or saved as a PICT file. New in this version: Instructions added in the "numerical values" window make it easier to use. Revised documentation and some minor aesthetic changes.
