Explanation: Radius of curvature, R = 0.4 m So, focal length, f = 0.4/2 = -0.2 m Object distance, u = -0.8 m Height of object, h = 0.2 m Using mirror's formula : v = -0.26 m So, the image distance is 0.26 m. The magnification of mirror is given by : h' = -0.065 m h' = -0.07 m Hence, the size of the image is 0.07 m
