Answer:
51.72 cm.
Step-by-step explanation:
We have been given that a pipe that is open at both ends has a fundamental frequency of 320 Hz when the speed of sound in air is 331 m/s. We are asked to find the length of the pipe.
First of all, we will find the wavelength using following formula.
We know that Hz is equal to .
Length of the pipe would be half of the wave-length.
Since the length of pipe is in meters, so we will convert it into cm.
1 m = 100 cm
Therefore, the length of the pipe would be 51.72 cm.
