Suppose the length of the tube used in our experiment is 4 m and a tuning fork of frequency 150 Hz is used in air where the speed of sound is 340.8 m/s? (Give your answers as integers. For this question, the length of the tube is of the entire plastic cylinder, and not the adjustable length of the air column.) (a) Calculate the number n to find the number of resonances afterwards. n = (b) How many resonances will be observed? N = resonances
