Question

I’m asking to list all possible ways (with formulas) to determine a speed of sound v using the following devices:

-function generator

-speaker

-microphone

-resonance tube

-positioning rod

-osciloscope

-digital multimeter

Answer 1

the function generator is connected to oscilloscope where we can view the waveform.

function generator we vary the frequency of the wave such that the frequency becomes resonance with the resonance tube frequency which has the waves from the microphone via speaker and function generator. The length is adjusted by positioning rod. by measuring from oscilloscope we can find the velocity of the sound wave from the frequency of corresponding function generator frequency.
