Start thinking about (and writing) the formal lab. Here is what you will need:
Basic structure of the lab report:
Basic structure of the lab report:
* Title
* Purpose of lab
* Data table - include all columns from your data, AND 1 more column: calculated f
* Find the average f, and the percent error between your average and the expected f from the lens.
* Find the average f, and the percent error between your average and the expected f from the lens.
* Sample calculation for focal length (your data table will have ALL of the calculated values, but there is only need for one calculation to be shown)
* Graph(s) if you made any (they are not required, but a graph of di versus do might be instructive)
* Conclusion - probably the biggest, most detailed part of the lab. Include the following:
- Give sources of error.
- Discuss how the image formation depends on object distance. Note if there "transition points", etc. This is the tough part of the conclusion (and the most mathematical).
- Discuss a technique for measuring the focal length of a concave lens (or convex mirror).
- Discuss the similarities between convex and concave mirrors and lenses.
- Give a general conclusion.
- Give sources of error.
