when you blow across the top of a soda bottle, it acts like a closed pipe. if the inside of the bottle is 0.150 m long, what is the fundamental frequency you hear? (speed of sound = 343 m/s) (unit = hz)

when you blow across the top of a soda bottle, it acts like a closed pipe. if the inside of the bottle is 0.150 m long, what is the fundamental frequency you hear? (speed of sound = 343 m/s) (unit = hz)

Answer

Explanation:

Step1: Recall the formula for fundamental frequency of closed - pipe

For a closed pipe, the fundamental frequency (f=\frac{v}{4L}), where (v) is the speed of sound and (L) is the length of the pipe.

Step2: Substitute the given values

Given (v = 343\space m/s) and (L=0.150\space m). Then (f=\frac{343}{4\times0.150}). Calculate (4\times0.150 = 0.6). So (f=\frac{343}{0.6}\approx572\space Hz).

Answer:

(572\space Hz)
