Linear? Quadratic? Exponential? Something else? Explain your answer. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac). BIUS Paragraph Arial 10pt ABC B P A 2 Tx x 2 points Save Answer Q 0 WORDS POWERED BY TINY Lens surfaces that bend outward are called converging. These lenses are marked with a positive lens power. Lens surfaces that bend inward are called diverging and have negative lens powers marked on them. Lenses of all types fall under the jurisdiction of the Lens Equation. This equation relates the focal length of the lens, f, to the distance and object is to the lens, p, and the distance the image is from the lens, 9. 1 1 1 =-+- fp q The heights of the object (h) and image (h) can also be related to the object distance and image distance by the magnification equation. h' h = q P Additionally, lens power, P, is often used to classify lenses, rather than focal lengths. Those quantities are related to each other via the power equation. 17 P =
