Pre-lab Question #1: The length of string in the below picture is 3.6 meters long. How
long is the wavelength?
Standing waves is a general wave phenomenon. This can also happen with sound
waves. For standing sound waves in an air column, there must be an node at the closed
end of the tube and a antinode near the open end. So, the first three conditions on
wavelength for a standing wave of sound in a tube of length L are
7:
31
= L
4
L
51

L
Pre-Lab Question #2: What is the next condition (fourth) condition on wavelength for
the standing wave of sound in a tube of length L? In this case, what would be the
wavelength of the sound waves if the tube is 70cm long? If the wave speed of sound is
340m/s, what is the frequency?
