(a) State the relation between object distance, image distance and the focal length of a spherical mirror.
(b) Draw a ray diagram to show the image formed by a concave mirror when an object is placed between the pole and focus of the mirror.
© A concave minor of focal length 15 cm forms an image of an object kept at a distance of 10 cm from the mirror. Find the position, nature and size of the image formed by it.
(a) The relation is 1/f=1/v+1/u
