Two wave pulses are heading toward each other on a string. One pulse is "up" and the other is the exact same shape, inverted (i.e. "down"). At the moment the pulses cross the string is perfectly horizontal. What happened to the energy in the wave?
Homework Answers
Solution) When two wave pulses identical in shape but inverted with respect to each other meet at any instant destructive interference is formed . So the entire energy of the system at that instant is stored in the form of POTENTIAL ENERGY within it . After they pass each other they regain their original shapes.

Two wave pulses travel on a string toward each other. The wave pulses can be described as y1 = 5/(((kx − ωt)^2) 2) and y2 = −5/(((kx + ωt − 6)2 )+2)' , where k = 1 rad/m and ω = 8 rad/s. At what instant do the two cancel everywhere? (Assume x is in meters and t is in seconds.) ???s At what point do the two pulses always cancel? ???m

Consider two identical and symmetrical wave pulses on a string. Suppose the first pulse reaches the fixed end of the string and is reflected back and then meets the second pulse. When the two pulses overlap exactly, the superposition principle predicts that the amplitude of the resultant pulses, at that moment, will be what factor times the amplitude of one of the original pulses? 0 1 -2 -1

When transverse positive and negative pulses that have the same symmetric shape and size but travel in opposite directions meet, is it necessary that there be a moment when the string or wire on which they move is flat? If so, how do the pulses "know" to continue moving on the string? Two people on each end of a long rope send off a wave pulse. If both wave pulses are on the same side of the rope, describe what...
