A standing wave is produced in a tube open at both ends. The fundamental frequency is 300 Hz. What is the length of the tube? (speed of the sound = 340 m s-1).

उत्तर
Data: For the tube open at both the ends,
n = 300 Hz and v = 340 m s-1 Ignoring end correction, the fundamental frequency of the tube is
n = `"v"/("2L")`
∴ L = `"v"/(2"n")=340/(2xx300)` = 0.566 m
The length of the tube open at both the ends is 0.5667 m.
