Short Answer

A 2.0-cm-tall object is to the left of a lens with a focal length of A second lens with a focal length of is to the right of the first lens.

a. Use ray tracing to find the position and height of the image. Do this accurately using a ruler or paper with a grid, then make measurements on your diagram.

b. Calculate the image position and height. Compare with your ray-tracing answers in part a.

a. The position and height of the image is given below in step.

b. The position of the image is away to the first lens.

See the step by step solution

Step by Step Solution

Part (a) step 1: Given Information 

We need to find the position and height of the image use ray tracing.

Part (a) step 2: Simplify

Consider :

Part (b) step 1: Given information

We need to calculate the image position and height.

Part (b) step 2: Simplify

Finding for the first lens:

Magnification for first lens is :

For the second lens :

Magnification of the second lens is :

Now, total magnification is:
