Unformatted text preview: the thickness of the lens (leaving all other parameters the same). Describe briefly. (5) (6) (7) (8) Lens equation (Tipler 31-19): 1/s + 1/s' = 1/f. Sign conventions: s, the distance of the object from the lens, is positive on the incident side (real object). s', the image distance, is positive on the transmission side (real image) and negative on the incident side (virtual object). f is positive for converging lenses, negative for diverging lenses. Linear magnification: m = y'/y = -s'/s. A negative magnification means the image is inverted....
