## Homework Statement

This is a 2 part problem but I figure out the first part. Heres the 1st problem and the solution:

7- Given a convergent lens which has a focal point f. An object is placed at distance p = [tex]\frac{4}{3}[/tex]f to the left of the lens. See the sketch.

Solution: q

_{1}= 4f, and is a real image

8- Now place a convergent lens with a same focal length f at a distance d = f behind the first lens. Determine q2, i.e., the image location measured with respect to the second lens # 2.

I will upload the actual image later.

Given:

p

_{1}= [tex]\frac{4}{3}[/tex]f

q

_{1}= 4f

f

_{1}= f

p

_{2}= ?

q

_{2}= ?

f

_{2}= f

## Homework Equations

[tex]\frac{1}{f}[/tex] = [tex]\frac{1}{p}[/tex]+[tex]\frac{1}{q}[/tex]

## The Attempt at a Solution

I would show my attempt at the solution but I don't know what is p

_{2}. How do I get p

_{2}?
