Question 1

If you stand closer to a concave mirror than a distance of one focal length, the image you see is

◦

real and inverted.

◦

real and upright.

◦

virtual and inverted.

◦

virtual and upright.

◦

none of the above because you do not get an image.

Question 2

Ilona and Olivia observe a virtual image formed by an object placed a distance

in front of a convex lens of focal length f. They argue about where to place a concave lens of focal length −f to have a virtual image at the same location relative to the lens that they had with the convex lens. Ilona says that the object should also be placed a distance

in front of the concave lens. Olivia says that this won't work. Which one, if either, is correct, and why?

◦

Ilona, because concave and convex lenses produce virtual images at equal image distances when the object distances are equal.

◦

Ilona, because both p and q are negative for a concave lens.

◦

Olivia, because both p and q are positive for a concave lens.

◦

Olivia, because if

, then p was p = ∞.

◦

Olivia, because if q = −f, then p was p = ∞.
