The divering lens has focal points at f1
WebAn object is 24 cm in front of a diverging lens that has a focal length of -14 cm. How far in front of the lens should the object be placed so that the size of its image is reduced by a factor of 2.2? Number i ! Units cm. Problem 15E: An object is placed 45 cm in front of a converging lens with a focal length of 20 cm. Draw a ray... WebA ray entering a diverging lens parallel to its axis seems to come from the focal point F. A ray passing through the center of either a converging or a diverging lens does not change direction. A ray entering a converging lens through its focal point exits parallel to its axis.
