# 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 concave mirror, with the object to be ignited positioned at the center of curvature of the 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 convex mirror. E) One cannot start a fire using a mirror, since mirrors form only virtual images.

###### FREE Expert Solution

To ignite the object, we need to use a mirror that converges reflected rays onto the object.

We cannot use a convex mirror because it diverges reflected light rays.
