Question

A traveling sinusoidal wave is propagating in the +x direction on a string. You make the following observations about the wave: - The Maximum transverse displacement of the string from its equilibrium position is 5cm - At a fixed instant in time, the distance between to points where the string has zero displacement from its equilibrium position is 40 cm. - At a fixed position a long the string, you observe that the string has zero displacement from its equilibrium position, and then it starts to be displaced. After 0.1 sec elapses, you again observe that the string has a zero displacement from its equilibrium position (at the position along the string). Write down the mathematical equation that describes this traveling wave. Your equation should have numerical values in it that you can deduce from the info given above

Explanation / Answer

A=max displacmnt=5

velocity=v=0.8/0.1=8

y=5sin(2pi/0.8){8t-x}
