    Velocity of sound in air in a closed air column

    I have no clue for the second position. Nothing seems to work or make sense to me wavelength= 3 x 0.475 m = 1.425 m velocity = 1.425 m x 500 Hz = 712.5 m/s that puts the %error off the chart.

    Velocity of sound in air in a closed air column

    If the first resonance position calculations are good what am I doing wrong for the second position?

    Velocity of sound in air in a closed air column

    So my calculations are good then?

    Velocity of sound in air in a closed air column

    Ok so I think I have the first resonance position figured out: average is 16.4 cm wavelength = (4 x 0.164 m) = 0.656 m velocity = wavelength x frequency = 0.656 x 500 = 328 m/s velocity with temperature = 343.4 m/s percent error = [(343.4 - 328) / 343.4] x 100 = 4.5% The second...

    Velocity of sound in air in a closed air column

    Does this sound right? First resonance position: I get the average at 32.9 cm wavelength = 66cm - 12.3 cm= 53.7 cm = 0.537 m velocity with wavelength = 0.537 m (500Hz) = 268.5 m/s velocity with temperature = 331.4 + 0.6(20C) = 343.4 m/s Second resonance position: 47.6 cm x 4 =...

    Velocity of sound in air in a closed air column

    Is this what you mean: First resonance position 1. 16.5 x 4 = 66 cm 2. 16.3 x (5/4) = 20.375 cm 3. 16.4 x (3/4) = 12.3 cm

    Velocity of sound in air in a closed air column

    It would really help to see an example? I'm still not getting it

    Velocity of sound in air in a closed air column

    Am I missing something and doing this all wrong? Experiment and data: The level of water in the glass tube was adjusted by raising the supply tank until the sound from the tuning fork was at its loudest. This level corresponds to first resonance position and it was recorded. The...
