Question

location 1 cm to the right of the lens magnification 2 Two converging lenses with f1 = 23 cm and f2 = 34 cm are located 1.50 m apart as shown in thefollowing figure. An object is placed 51 cm in front of the lens on the left. (a) Construct a ray diagram for the first lens.(Do this on paper. Your instructor may ask you to turn in thiswork.) Find the location and magnification of the image produced by thefirst lens. (b) Construct a ray diagram for the second lens, using the imagefrom part (a) as the object. (Do this on paper. Your instructor mayask you to turn in this work.) Where is the image produced by the second lens? What is the overall magnification?

Explanation / Answer

MAGNIFICATION DUE to the first lens=v1/u1=41.9/51=0.8215 MAGNIFICATION DUE to the second lens=v2/u2 u2=150-41.9=108.1cm v2=49.6cm so now magnification due to second lens=49.6/108.1=0.4588 overall magnification=magnification due to first lens*magnificationdue to second lens.=0.8215*0.4588=0.3769
