Bob has two tubes that both support (or hold) standing sound waves with the same
Bob has two tubes that both support (or hold) standing sound waves with the same frequency. Tube A has two open ends, and Tube B has one open end and one closed end. The value of the fundamental frequency for both tubes is the same.
(a) How many wavelengths long is Tube A for the fundamental mode (or frequency)?
(b) How many (of the same) wavelengths long is Tube B for the fundamental mode (or frequency)?

a) tube A's length is half the wavelength
b) tube B's length is three fourth of the wavelenght.
Explanation: for a pipe with both ends open, antinodes form at both ends and a node forms in the midpoint of the tube.
For a pipe with one end open, a node forms at the closed end and an antinode at the Open end.
