     Mirrors are three types:

                                 1) Plane Mirror

                                 2) Concave mirror

                                 3) Convex Mirror

                We will use geometrical optics: light propagates in straight lines until its direction is changed by reflection or refraction. When we see an object directly, light comes to us straight from the object. When we use mirrors, we see light that seems to come straight from the object but actually doesn’t. Thus we see an image (of the object), which may have a different position, size, or shape than the actual object.
