Phys 100 Fall 2011 Concepts of Physics: Homework 8 Due: 26 October 2011 In order to receive full credit, you must show all work, calculations and provide complete reasons and explanations for your solutions. 1 Hobson, Physics: Concepts and Connections, 5ed Ch. 9 Review Question 6, page 221. 2 Interference of waves on a string Two rectangular wave pulses move along a string with speeds 1cm/s. Initially the string appears as illustrated. -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 cm In the following questions the times refer to the time after this instant. a) Illustrate the appearance of the string after 2s has passed. Use the axes on the attached sheet to do this. b) Illustrate the appearance of the string after 3s has passed. Use the axes on the attached sheet to do this. 3 Interference of pulses Various pulses approach each other as illustrated. Case A Case B Case C Case D 1
