Getting started on lab

P1.  Review quiz (in mailbox) - key is posted on blog.

Lab stuff -

2.  Make sure you have a neat data table (remember units).

3.  Make sure you have calculated the experimental focal lengths (f) using the lens equation:

1/f = 1/di + 1/do

In the lab, you'll need to show a sample calculation (from your data).  See sample below.

4. Start thinking about sources of error - also, why is your calculated f different from the f obtained by focusing an image of a tree outside onto your screen?

5.  Look at your data.  Is there a point when the images go from smaller to bigger?  Real to virtual?  Are those points related to the focal length?

On Monday, bring this work as well as your notebook for me to check.

Thanks, and have a great weekend!
