Answer» Explanation: LIGHT rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis after reflecting from the mirror. This point is known as the principal FOCUS of the concave mirror. A concave mirror gives an ERECT and enlarged IMAGE of an object held between pole and principal focus of the mirror. |
