(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two sinusoidal waves with equal wavelengths travel along a string in opposite directions at 7.72 m/s. The time between two successive instants when the antinodes are at a maximum height is 0.324 s. What is the wavelength (in m)?

2. Relevant equations

vt=x

Also,

Propagation speed = wavelength * frequency = wavelength / period time

3. The attempt at a solution

I tried many, many different ways to solve this equation but ultimately I keep getting the wrong answer.. Here is one of the attempts:

The distance between two successive antinodes or two successive nodes is equal to the wavelength of the wave. I figured out the distance based on the speed of the wave and the time between two antinodes with vt = x (since there is no acceleration).

(7.72)(0.324)= 2.50128 m

Yet it is not the right answer? Can anyone give me any more insight on what I can do..?
