The student connects the speaker to a function generator and sweeps the frequency of the generator from 80H z to 400.0Hz. The student measures the amplitude of the signal from the microphone while doing this and observes maxima in the microphone signal at frequencies of 126Hz, 189H z, 252H z, 315H z, and 378H z. What is the length of the tube? (Use 343m / s as the speed of sound.) m Submit You have used 0 of 5 attempts Save H5.3 2 points possible (graded) Ed x EM ENG 1:25 PM US 2022-10-22 1
