# Problem: Suppose you wanted to start a fire using sunlight and a mirror. Which of the following statements is most accurate? a) It would be best to use a plane mirror. b) It would be best to use a convex mirror. c) It would be best to use a concave mirror, with the object to be ignited positioned halfway between the mirror and its center of curvature. d) It would be best to use a concave mirror, with the object to be ignited positioned at the center of curvature of the mirror. e) One cannot start a fire using a mirror, since mirrors form only virtual images.
