A lens can be moved forward or back to produce an image on film a the back of the camera. For a certain camera, with the distance i between the lens and the film set at f 6.01 cm, parallel light rays from a very distant object o converge to a point image on the film, as shown. The object is now brought closer, to a distance of p 185 cm, and the lens-film distance is adjusted so that an inverted real image form on the film (Figure (b)).

Explanation / Answer

a)

from thin-lens formula is

1/f = 1/i +1/p

=>i=(1/f -1/p)-1 =(1/6.01 - 1/185)

i=6.21 cm

b)

the change in the lens-film distance is

=6.21-6.01=0.2 cm
