Two converging lenses, each having a focal length equal to 8 cm, are separated by 35 cm. An object is 30 cm to the left of the first lens.
(a) Find the position of the final image using both a ray diagram and the thinlens equation
(c) What is the overall lateral magnification?
What I did:
s1' = f1s1/(s1f1)
s1' = (8cm)(35cm)/(35cm8cm) = 10.37cm
m1 =  s1'/s = 10.37cm/35cm = .296285cm
s2' = f2s2/(s2f2)
s2 = 35cm30cm = 5cm
s2' = (8cm)(5cm)/(5cm8cm) = 13.333cm
m2 =  s2'/s =  (13.333cm)/5cm = 2.666cm
For question a isn't it 35cm+s1'+s2'=32.04cm or 32cm? This answer was marked wrong can anyone tell me what I did wrong?
For question c  m = m1*m2 = .296285cm*2.666cm = .78989581cm but this is again wrong
Please help, thanks!
