Imagine a  wave traveling is  stretched to total length of 3.4m and  takes 2.9s to travel the length back again. What could be the propagation speed of the wave, in m/s?  Then if a  periodic standing wave is created in the same stretched to the same length It contains three antinodes and four nodes . What is the frequency of the wave, in Hz?
