Lecture 26 Outline of Last Lecture I. Diverging Lens a. Equation for magnification same as for mirrors. i. m = hi/ho = -di/do b. Lens equation same as mirror equation. i. 1/f = 1/do + 1/di c. Real images are on opposite side of lens as object, virtual images are on the same side of lens as object. d. Object placed between F (focal point) and 2F (twice focal length from center) creates a real image of increased size. e. Object placed further than 2F form center of lens creates a real image of reduced size. f. Object placed within focal length creates a virtual image larger than object. Physics 012 1st Edition
