Rules:
-Collaboration
between team members is encouraged,
-The
authors should present the solution on a blank sheet with their names on it.
Members of a team should submit together.
-Solutions
should include “self-explained” diagrams/sketches, with minimal wording. Neat
presentation will count toward the problem grading.
1.- Two waves with the same angular frequency, wave number, and
amplitude ω, k, A, respectively, but differ in a phase Ф, are to be
superposed (added). By using trigonometric identities, and doing some algebra,
provide the total amplitude as a function of Ф
2.- Using your knowledge about (sound) waves, explain as much as
you can the physics behind the guitar.
3.- Produce the interference of circular water waves from two
point sources, take a picture of it or short movies clip, and submit on a CD.
