We’re given a concave spherical mirror with radius of curvature R = 10.8 cm, so the focal length is f = R/2 = 5.4 cm. The object (the glowing bulb) is placed at a distance of 15 cm from the mirror. For a mirror, the image distance v can be found from the Gaussian form 1/v = 1/f - 1/u when we treat distances as magnitudes and use the standard conven......Login to view full explanation
