REFRACTION+USING+A+SIMULATION

IB PHYSICS > PRACTICAL WORK > IB IA EXPERIMENTS [|IA criteria checklist.doc] - always a good idea to look at this before submitting your work. =PRACTICAL: REFRACTION USING A SIMULATION=

PROCEDURE:
Choose a medium (not air or vacuum) Raw data: vary angle of incidence and measure angle of refraction. Record the results in Excel. Plot angle i against angle r. State why the relationship is not proportional. Processed data: Plot sine i (vertical axis) against sine r (horizontal axis). Add a trendline. Calculate the gradient of the trendline. What is the significance of the gradient? Repeat for a second medium.
 * REFRACTIVE INDEX**

For a fixed incident wavelength, plot refracted wavelength against refractive index for all the media in the simulation. Linearise the graph. Calculate the gradient of the linear trendline. Does it have a physical significance?
 * DIFFERENT MEDIA**

REPORT:
The data and the graphs.
