Transcribed Image Text:A converging lens with a 44cm focal length is placed 23cm to the right of an object. Where should a second lens with a 60cm focal length be placed so the resultant image has a magnification of 2.5 and is inverted? Give your answer in centimeters distance to the right of the first lens.
Expert Solution
Step 1

The lens formula is 

1v-1u=1f

where v is the image distance, u is the object distance and f is the focal length

The magnification of lens is 

m=vu
