Question
Two-lens systems. In the figure, an object 0 (the object) stands on the common central axis of two thin, symmetric lenses. Lens 1 is mounted closer to 0, which is at object distance py. Lens 2 is mounted within the farther region, at distance d. For this problem, p1=9.3 cm, lens 1 is diverging, d -12 cm, and lens 2 is converging. The distance between the lens and either focal point is 5.2 cm for lens'!, and 6.6 cm for lens 2. (You need image produced sign). Find (a) the image distance i2 for the image produce y Inducting sign Also, determine whether the final image is (c) real or virtual and (d) inverted or non invertedExplanation / Answer
lens 1
1/p1 + 1/q1 = 1/f1
(1/9.3)+(1/q1) = -(1/5.2)
q1 = -3.33 cm
m1 = -q1/p1 = 3.33/9.3 = 0.358
lens 2
p2 = 12+3.33 = 15.33 cm
(1/p2)+(1/q2)=(1/f2)
(1/15.33) + (/q2) = (1/6.6)
q2 = 11.58 cm
m2 = -q2/p2 = -0.755
b) M = m1*m2 = -0.27
c) real
d) inverted
