The first half of both pulses have same positive value. Hence
they will be added. The second half of both pulses have opposite
values and hence they will be cancelled. Hence the resultant pulse
is shown below

Two wave pulses are sent in opposite directions down a long rope. Here is a diagram of an example pulse. Pulse (light blue) 2 y in meters "Sea level" (dark blue) 0.00 meters 2 3 5 x in meters If they are both "crests," we observe that when they meet, they bounce off each other and become troughs. Obounce off each other and remain crests. O cancel each other. O pass through each other.

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...
