The magnification of an object is defined as m=h′h, where h′ is the height of the image and h is the height of the object. if the image is inverted, then h′ is negative. place the pencil 90 cm from the lens. what is the magnification of the image (be sure the curvature radius is still 0.6 m and the refractive index is 1.5)?
