+-/3 points My Notes The graphs below may represent either a picture of the shape of a wave on a string at a particular instant in time, t1, or the transverse (up and down) velocity of the mass points of that string at that time Depending on what they are, the wave on the string may be: 1. a right going traveling wave 2. a left going traveling wave 3. a part of a standing wave growing in amplitude at time t 4. a part of a standing wave shrinking in amplitude at time t For each of the following cases, decide what the wave is doing and choose one of the four number(1)-(4) or none (N) L. Graph A is a graph of the string's shape and graph B is a graph of the string's velocity. ii. Graph A is a graph of both the string's shape and the string's velocity. i. Graph B is a graph of the string's shape and graph A is a graph of the string's velocity. -Select-

Explanation / Answer

i )

Option " 1 "

here parts of string that is sloping down is moving in upward direction vice versa

so it is right going travelling wave.

ii )

Option " 3 "

the positive parts are having positive velocities and negative having negative velocities so amplitude is growing but no change

iii )

option 2

here slopes of the string upward is in upward and downward is in downward direction

so it is left moving..
