of a standing wave is 16.8 cm. The hand generating
the pulses moves up and down through
a complete cycle 2.22 times every 7.59 s.
Find the velocity of the wave.
Answer in units of m/s.

Answer 1

1) the sound goes over and back
... 2 w =5.7 * 343

2)velocity = frequency * wavelength
... v = (2.22 / 7.59) * .168 m
