02.50: Two thin lenses each with a focal length of +10 cm are located 30 cm apart with their optical axes aligned as shown. An object is placed 35 cm from the first lens. After the light has passed through both lenses, at what distance from the second lens will the final image be formed?

  05.41: In a system of lenses, it is reported that when q7az;ym6 +xzn the calculation of the magnification was performed on a diverging lens that has focal length of magnitude f, the image zn;qmy7zx+ 6asize was identical to that of the object. How is this possible?
