A) When we are looking at our eye in a flat mirror, how does the light travel between the different parts of the eye and the mirror to create the images we see? If someone was looking over our shoulder at the same eye, what paths would the lights take to form the images that the person would see?
B) Since it is a known fact that light transmits energy and that bright lights transmits more energy than dim light, do interference effects violate conservation of energy and why?
