Mirrors and lenses have similar image formation characteristics. Converging mirrors and converging lenses can both make real or virtual images that can be larger, smaller, or the same size as the object depending on where the object is relative to the focal point. Diverging mirrors and lenses only make virtual, upright images that are smaller than the object. The relationships between focal length, object distance, and image distance are the same for mirrors and lenses. The mirror and lens equation can be used to mathematically located images and determine their characteristics.
