SUMMARY
The discussion focuses on calculating the three longest wavelengths for standing sound waves in a 128 cm tube, specifically analyzing two configurations: open at both ends and open at one end while closed at the other. For a tube open at both ends, the fundamental wavelength is 256 cm, while for a tube open at one end and closed at the other, the fundamental wavelength is 512 cm. The relationship between wavelength, velocity, and frequency is established using the equation W=V/F, where W represents wavelength, V is velocity, and F is frequency.
