    X coordinate in the last part wasn't this, it was greater then 1...the diagram clearly showed that it had to be between π/3 (the upper boumdary calculated for area in the previous part ) and π/2

    So if you do by this method, the mean time is 9.4±0.1s so isn't max value 9.41 and min 9.39? Error in T will then be 0.005 And if we apply the other rule that if a quantity is being multiplied or divided by a number, then the error in the calculated quantity is error in previous quantity times...

    Ok thank u so much! Just a little thing, we need the intensity of sound wave before reflection as well as mentioned in the formula so I think that needs to be measured as well

    And plz tell me how will the intensity be calculated from the amplitude. Amplitude² is proportional to intensity but how will the value be calculated as we don't know of any constant in this equation. P.s should't the microphone be placed beside the speaker with a barrier in between? And to...

    Physics: Post your doubts here!

    I think it's not important to show the pump specifically, we can just show a tube and write 'to pump' and yes a pressure guage instead of the manometer which will be shown as a circle and labelled. Manometer will also work but then we need to explain it in detail that how value for pressure will...
