Vedclass · Answer

(B) For a concave mirror,when an object is placed at the focus $(u = -f)$,the image is formed at infinity. However,for a convex mirror,if an object is placed at a distance equal to the focal length $(u = -f)$,the image is formed behind the mirror at a distance of $f/2$ from the pole. Since the question specifies a 'spherical mirror' without distinguishing between concave and convex,the image formation depends on the type of mirror. Therefore,the image may be at infinity (if the mirror is concave) or at another position (if the mirror is convex). Thus,the correct option is that the image 'may be at infinity'.

The distance of an object from a spherical mirror is equal to the focal length of the mirror. Then the image:
