(a) Write relation between u, v, f for lens and for mirrors, where u, v, f are object distance, image distance and focal length respectively.
(b) The magnification produced by a plane mirror is m = + 4. Write the information
about the image given by this statement.
© Draw a ray diagram for the following and show the formation of the images in case of concave mirror when the object is placed in:
(i) between the pole and focus point
(ii) on centre of curvature
(a) Mirror formula 1/f = 1/v + 1/u
Lens formula 1/f = 1/v - 1/u
(b) It means the height of image is 4 times the height of object and image is virtual.
© (i) Between the pole and focus point.
(ii) On centre of curvature.
