The speed of sound in air is around 345 m/s. a tuning fork vibrates at 850 hz above the open end of the sound resonance tube. what is the wavelength (in cm) of the sound waves in the tube? never include units with a numerical answer.

For the development of this problem it is necessary to apply the concepts related to the wavelength depending on the frequency and speed of light.

By definition we know that frequency can be expressed as

Where,

v = Velocity

Wavelength

Our values are

Re-arrange to find Wavelength

Converting to centimeters,

Therefore the wavelength of the sound waves in the tube is 40.58cm

answer is c

explanation:

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
