    A 0.75m long instrument tube has two open sides as a standing sound wave moves through it (speed of sound is 343 m/s). You count 4 nodes in the tube. (a) Find the wavelength and frequency. (b) You suddenly close both ends of the tube. The number of nodes doesn't change, but their positions do What is different about the air pressure and displacement? How did the wavelength and frequency change?

    A tube, open at the left end and closed at the right, has standing-wave patterns at frequencies of 198 Hz and 330 Hz. The speed of sound in air is 343 m/s. The lowest two harmonics (normal modes) that these two standing waves could be are m = and The frequency of the fundamental (m = 1) is Hz. The wavelength of the fundamental mode is m. The tube is m long
