Answer:
168 Hz, 280 Hz and 392 Hz
Explanation:
The resonant frequencies for a closed pipe at one end is given by :
, n = 1,3,5...
The fundamental frequency, f₁ = v/4l = 56 Hz
For first overtone, put n = 3
For second overtone, put n = 5
For third overtone, put n = 7
So, the first three overtones are 168 Hz, 280 Hz and 392 Hz.
