What is the frequency of the 1 st harmonic for this tube when both sides are opened? 200 Hz 250 Hz 300 Hz 350 Hz 400 Hz numbers 20-21 A 1.2 m closed tube resonates at the 5th harmonic. What is the wavelength? 0.84 m 0.96 m 1.08 m 1.20 m 1.32 m Which of the following distances from the open end will a pressure antinode be found? 0.84 m 0.96 m 1.08 m 1.20 m 1.32 m numbers 22-23 Two speakers emit a sinusoidal tone of 85 Hz and are in phase. The speakers are 7 m and the speed of sound is 340 m/s. What is the closest distance to either speaker, along a line connecting the speakers, where completely constructive interference is observed? 3.0 m 2.5 m 2.0 m 1.5 m 1.0 m What is the closest distance to either speaker, along a line connecting the speakers, where completely destructive interference is observed? 2.5 m 2.0 m 1.5 m 1.0 m 0.5 m
