The amplitude of a standing sound wave in a long pipe closed at the left end is sketched below.00The vertical axis is the maximum displacement of the air, and the horizontal axis is along the length of the pipe. What is the harmonic number for the mode ofoscillation illustrated?5.You are correct.Your receipt no. is 160-68Previous TriesThe length of the pipe is 0.350 m. What is the pitch (frequency) of the sound? Use 340 m/s for the speed of sound in air.1.21x103 HzYou are correct.Your receipt no. is 160-6588 eThe pipe is now held vertically, and a small amount of water is poured inside the pipe. The first harmonic frequency is then measured to be 315.7 Hz. Measuringfrom the bottom of the pipe, what is the level of the water?0.0269mPrevious TriesSince we know the frequency of harmonic 1, and the speed of sound, we can calculate the effective length of the pipe with water in the bottom. The full lengthminus the effective length must be the length of the water.Submit AnswerIncorrect. Tries 4/12 Previous TriesSend FeedbackPost Discussion
