Answer:
504.41 Hz
Explanation:
Given,
Height of the bottle, h = 26 cm
height of the water, l = 9 cm
Length of the pipe
L =h - l
L =26 - 9 = 17 cm
Fundamental frequency of closed-open pipe
[tex]f = \dfrac{v}{4L}[/tex]
v = speed of sound, v = 343 m/s
[tex]f = \dfrac{343}{4\times 0.17}[/tex]
f = 504.41 Hz
Fundamental frequency of bottle is equal to 504.41 Hz
