Question

A teacher is examining laboratory supplies with a diverging lens. The lens has a focal length of magnitude 19.2 cm. The lens is always held between the teacher's eye and the object under study. However, the distance between the lens and the object is different for each object that the teacher observes. Determine the image location and magnification for each of the following three objects. In addition, determine whether the image is real or virtual, whether it is upright or inverted, and whether it makes the object appear larger or smaller than actual size. (a) The object lies 38.4 cm behind the lens. Determine the image location. (Enter the magnitude in cm.) cm Determine the magnification. M= Select all of the following that apply to the image formed i part (a). real virtual upright inverted enlarged shrunken (b) The object lies 19.2 cm behind the lens. Determine the image location. (Enter the magnitude in cm.) cm Determine the magnification. M= Select all of the following that apply to the image formed in part (b). real virtual upright inverted enlarged shrunken
