(a) What is the distance between an object and its real image formed by a thin converging lens with focal length f = 16 cm, if the object distance is 45 cm? (b) What is the minimum object-image distance for a real image formed by that lens?

Solutions

Expert Solution

a)   Here, 1/v + 1/u = 1/f

=> 1/v = 1/16 - 1/45

=> v =   24.827 cm

Thus,    distance between an object and its real image   = v + u

                                                                                     =   24.827 + 45

                                                                                      =   69.827 cm

b) the minimum object-image distance for a real image = 4 * focal length

                                                                                          = 4 * 16

                                                                                          = 64 cm
