Explanation:
Explanation:
Given that, two successive resonant frequencies for an open ended organ pipe (open at both ends) are 801 Hz and 890 Hz.
(a) The frequency in case of organ pipe open at both ends is given by :
L is the length of the pipe
if f = 801 Hz
.........(2)
If f = 890 Hz for (n+1)
So, .........(2)
Dividing equation (1) and (2) we get:
On solving,
n = 9
(b) The speed of sound in air, v = 343 m/s
L = 1.92 meters
Hence, this is the required solution.
