The distance between two nearest nodes of
a standing wave is 17.3 cm. Hand generated
pulses move up and down through a complete
cycle four times every seven seconds.
Find the velocity of the wave.
Answer in units of m/s.

frequency=4cycles/7seconds

velocity=frequency*wavelength
= 4/7 * 2*17.3 cm/sec change to m/s
