Physics 6 Tutorial 7 - Interference

Home

Summary

In this tutorial we will look at how light interferes, using both Division of Amplitude and Division of Wavefront.  We will see what is meant by these terms.  We will discuss the difference between geometrical and optical path difference. We will use the ideas to look at interference effects in thin films, such as oil on water, and thin wedges.  We then go on to consider Young's Double Slits
