The image produced by a convex mirror is always The image produced by a convex mirror is always Solution The image produced by a convex mirror is always closer to the mirror than it would be in a plane mirror for the same object distance.A convex mirror forms only virtual images, so the magnification produced by a convex mirror is always positive . For a convex mirror: f is positive ?f > 0 Since the object is on the left u<0 1/v=1/f?1/u 1/v or v is positive if the image is at the back of the mirror. Therefore the image is virtual and always upright whatever be the value of u .
