A tube of length 5 cm. Which is open at both ends, vibrates with two different resonances in a given physical situation. They are the standing waves with the longest and fifth-longest possible wavelengths for the tube. Make one drawing of the wave for each of these two resonances, label the following things on each of your drawings:
The physical quantity that the wave represents. In your drawing, what quantity is plotted on the vertical axis vs. horizontal position in the tube?
Where the tube ends on both sides and, at those endpoints, whether this physical quantity is a node or antinode.
The endpoints of one full wavelength λ, and the numerical value of this wavelength
