  1. A convex lens with a focal length of magnitude 4.0 cm and a concave lens with a focal length of magnitude 10 cm are separated by a distance of 18 cm as shown in the diagram below. The convex lens is on the left, and the concave lens is on the right. An object is then placed 6.0 cm to the left of the convex lens.
  1. Locate the final image. State the distance of the final image to the right or to the left of the concave lens.
  2. What is the total magnification of the object? Is the final image upright or inverted? Is the final image real or virtual?
  3. Where would an observer have to be located to be able to see the final image?
  4. With the use of paper, pencil, and a ruler, construct a ray diagram. You may choose the scale. (Prof recommends a scale of 1 cm →0.5 cm). For more room on a page, they also recommend working along the lengthwise side of a standard sheet of paper.)

NOTE: In the problem, it says that there is a diagram below - this is NOT true - we must draw it to scale

A concave lens has a focal length of magnitude 10 cm. It is placed a distance of 25 cm from a concave mirror with a focal length of magnitude 15 cm. An object is set a distance of 22 cm in front of the lens. The observer is at the same location as the object, so the light from the object goes through the lens, reflects off the mirror, and comes back through the lens to the observer. Draw the...
