Module 5Test: Hint 3

The first part should be straight forward enough. Simply copy the spreadsheet that I presented earlier in the module. You now have to choose a suitable range of x. The wavelength L is 7.11 m, so you should probably go up to 25 m, with about 50-100 points in between; i.e., increment x by about 0.25-0.50 m. (Remember to keep t fixed at t = 0).
