When an image is reflected off a convex mirror, how does the image appear to the eye?
Optics - Convex Mirror
  1. The image is magnified because a convex mirror is divergent.
  2. The image is magnified because a convex mirror is convergent.
  3. The image is reduced because a convex mirror is divergent.
  4. The image is reduced because a convex mirror is convergent.

When light rays pass through a convex lens, as in the image below, what happens to the rays and the perceived image of the object?
Optics - Convex Lens
  1. The light rays diverge, magnifying the perceived image.
  2. The light rays converge, magnifying the perceived image.
  3. The light rays diverge, reducing the perceived image.
  4. The light rays converge, reducing the perceived image.
