| A concave mirror curves inward like the inside surface of a hollow sphere. Light striking the surface of a concave mirror reflects inward, or converges. The size, position, and type of image—real or virtual—depends on the size and position of the object and the focal point of the mirror, or the place where light rays converge. In this illustration, an object is placed between a concave mirror and its focal point. The mirror forms a larger, upright, virtual image. |
