The speed of sound in an air column of 80 cm closed at one end is 320 m/s. Find the natural frequencies of air column between 20 Hz and 2000 Hz.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
100 (2n + 1) Hz where n = 0, 1, 2, 3, ...., 9
Sol. fundamental frequency of air column
f = 
= 100
other frequency which resonates are
f = 100 (2n +1) n = 0, 1, 2, 3 ........
here f 
2 kHz
