Homework Answers
The Amplitude of Wave P is positive for all the time but the amplitude of wave Q positive for the half time period and negative for another half time period. So when the two waves collide we will get a wave which has positive amplitude for a full time period. Hence option 5 is correct.

At t = 0, the instantaneous position of two pulses moving along a taut string with a speed v = 23.2 cm/s are as shown in the diagram below. Each unit on the horizontal axis is 4.0 cm and each unit on the vertical axis is 3.0 cm. (The peak of pulse 2 is exactly on a half unit of the horizontal axis.) (a) At what location will the resultant of the two pulses have maximum amplitude? cm (b) At...
