An object is placed at a distance of twenty centimeters in front of a concave mirror having a focal length of ten centimeters. Where will the image be formed?

💡 Solution & Explanation

Using the mirror formula one over f equals one over v plus one over u, substituting focal length minus ten and object distance minus twenty gives image distance equal to minus twenty centimeters. This means the real and inverted image is formed exactly at the center of curvature. Concave mirrors form real images for all object positions beyond the focal point except when placed between pole and focus.
