일반물리학 1 — Waves-II: Problem 38

38 One of the harmonic frequencies of tube A with two open ends is 400 Hz. The next-highest harmonic frequency is 480 Hz. (a) What harmonic frequency is next highest after the harmonic frequency 160 Hz? (b) What is the number of this next-highest harmonic? One of the harmonic frequencies of tube B with only one open end is 1080 Hz. The next-highest harmonic frequency is 1320 Hz. (c) What harmonic frequency is next highest after the harmonic frequency 600 Hz? (d) What is the number of this next-highest harmonic?
