The speed of sound in air is 345 m/s. A tuning fork vibrates above the open end of a sound resonance tube. If sound waves have wavelengths 63-cm in the tube, what is the frequency (in Hertz) of the tuning fork? Never include units with a numerical answer.

To develop this problem it is necessary to apply the concept of Frequency based on speed and wavelength.

According to the definition the frequency can be expressed as

[tex]f = \frac{v}{\lambda}[/tex]

Where,

v = Velocity

[tex]\lambda =[/tex] Wavelength

Our value are given by,

v = 345m/s

[tex]\lambda = 63cm[/tex]

Replacing

[tex]f = \frac{345}{0.63}[/tex]

[tex]f = 547.61Hz[/tex]

Therefore the frequency of the tuning fork is 547.61Hz
