Do not use the Lab Manual for this Lab Activity. Rather review the experiment in the Lab Supplement given to you at the beginning of the class.

Review the following web materials before performing the Lab Activity

1. Images formed by mirrors and lenses

Lab Report should include:

1. Objective

2. Experimental Procedures

3. Data tables 1 - 5

4. Graphs for tables 1, 4

5. Calculations

6. Questions: 

a) Describe the properties of the image formed by the converging lens. How does magnification factor depend on object distance?  

b) Explain why for a given screen-to-object distance there are two lens positions where a clear image is formed.

c) For a given focal length f what is the minimum screen-to-object distance when a clear image is formed. What is the limit in your case?

d) Describe the properties of the image formed by the concave mirror. How does magnification factor depend on object distance?

e) What are the sources of experimental errors in this experiment?

7. Discussion and Conclusion
