This will be your last upload assignment.

Investigate the relationship between the distance form a point on a nodal line to each wave source in a water wave ripple tank.

You will be using this applet.

Introduction to the Ripple Tank	Measuring Wavelength
Measuring to the Nodal Line	Using the Spreadsheet Template

This activity is experimental.

I am expecting your results will vary a bit from the expected. Please let me know how closely your results were to theory. I am interested in how well the simulation works.

You might want to research the path difference here.

Here is the spreadsheet template.

How well can you collect and interpret data	You have collected data, but there are no clear trends, possibly related to a misunderstanding of portions of the procedure.	Your data has errors, probably related to improperly conducted measurement. You have difficulty applying interference concepts to the interpretation.	You have carefully collected your data. There is a clear trend with some measurement error. You can interpret the data in relation to interference of waves.	You have carefully collected your data. There is a clear trend with some measurement error. You can interpret the data in relation to interference of waves and you can provide a mathematical example and a prediction or extension.
