1. The problem statement, all variables and given/known data Two converging lenses of focal length=27cm are placed 16.5cm apart. If an object is placed 35cm in front of the first lens, where will the final image be produced? What will be the total magnification? 2. Relevant equations 1/f=1/di+1/do do2=D-di1 M=-di/do 3. The attempt at a solution 1/f1=1/di1+1/do1 1/27=1/35+1/di1 di1=118.125cm do2=D-di1 do2=16.5-116.125 do2=-101.625cm 1/f2=1/do2+1/di2 1/27=1/-101.625+1/di2 di2=21.33cm<<<<< Mt=M1M2=(-21.33/-101.626)(118.125/35)=0.785X<<<<< If something is wrong, please show me my mistake, and if it's right please let me know!
