A uniform narrow tube 1.70 m long is open at both ends. It resonates at two successive harmonics of frequencies 275 Hz and 330 Hz.What is ($a$) the fundamental frequency, and ($b$) the speed of sound in the gas in the tube?

Step 1
Harmonics are the frequencies at which a system resonates. In the case of a tube open at both ends, the harmonics are given by the equation: f = (n * v) / (2L) where f is the frequency, n is the harmonic number, v is the speed of sound, and L is the length of Show more…
