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

Answer:

The length of the closed tube is

0.81 m

Explanation:

Formula used :

$Speed = wavelength\times frequency$

$v = \lambda \times \nu$

Speed = v = 346 m/s

$\nu = 426.7 Hz$

$346 = \lambda \times 426.7$

$\lambda = \frac{326}{426.7}$

wavelength = 0.81 m
