An object is placed 4 cm away from a concave lens of focal length 3 cm. A convex lens of focal length 5 cm is placed 4 cm away from the concave lens in the same direction (so the distance between convex lens and the object is 8 cm).

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...
