After completing part 2 of this lab, you will be able to: A. make an interference pattern with two sources, and determine the ways to change the pattern. B. Find points of constructive and destructive interference by eye and by using the detectors. C. Put up a barrier to see how the waves move through one or two slits. What sort of pattern do the slits create? How can you change this pattern? Develop your understanding Open the Interference screen, then explore to make water waves with varying patterns.
