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 lensrf(p7j 1rk8g xes, it is reported that when the calculation of the magnification was performerg(f rk7xp8j1d on a diverging lens that has focal length of magnitude f, the image size was identical to that of the object. How is this possible?

  07.43: Which of the following best represqyh +;w+vv )asents the ray diagram construction for finding the image formed for the virs+qvwv )+h;yatual object shown? The solid dots on either side of the lens locate the equal magnitude foci of the lens.

  15.34: An upward-pointing ih-td vq8ct 3x- dtux.:a0.wm object is placed 15.0 cm to the left of a lens system. The first lens is convex with focal length 10.0 cm. The second lens is convex with focal length 10 c???? and its location from the first lens is varied from 10 cm away to 110 cm away. Which one of the following choices best represents the dex t -tc duq .hdv0xi-3maw8:t.scription of the final image formed as the second lens is moved from x = 10 cm to x = 110 cm from the first lens?
