Question

Quizplus · Accepted Answer

The mirror equation is 1/f = 1/v + 1/u. For a concave mirror, the focal length (f) is negative and equals half the radius of curvature, so f = -25 cm. Given u = -40 cm (object distance is negative for a real object in mirror equations), solving for v gives a negative value, indicating a real image on the same side as the object. The magnification equation, m = -v/u, results in a value greater than 1 (in magnitude), indicating the image is enlarged. Since m is negative, the image is inverted.
