Question

A 426.7 Hz tuning fork is resonating in a closed tube on a warm day when the speed of sound is 346 m/s. What is the length of the closed tube? 0.20 m 0.31 m 0.81 m 1.23 m

Answer 1

The length of the closed tube is

0.81 m

Step-by-step explanation:

Formula used :

`Speed = wavelength* frequency`

`v = \lambda * \\u`

Speed = v = 346 m/s

`\\u = 426.7 Hz`

`346 = \lambda * 426.7`

`\lambda = (326)/(426.7)`

wavelength = 0.81 m
