In the film, "Enter the Dragon," the last scene involves a fight scence in a house of mirrors. Bruce Lee breaks the mirrors to avoid the problem of tracking the villain due to too many reflections. If that house of mirrors were all concave or convex, what would have happened to the images? Explain the effect in terms of reflection, sign conventions, and mirror equations.
