Mirror, Mirror on the Wall… Let’s now consider mirrors, another very familiar type of optics in our everyday lives. We should all be familiar with flat mirrors, they hang in our bathrooms, in our cars as the primary rearview mirrors, and in many light fixtures, reflecting and concentrating light for our convenience. Plus, like lenses, mirrors have three shapes: flat, like the plano lens, concave, and convex. Yet, the results of using a convex lens is not the same as a convex mirror.
