## Homework Statement

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?

## Homework Equations

1/f=1/di+1/do

do2=D-di1

M=-di/do

## 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<<<<<
