    Today's Lecture's summary :
    1) Soundwaves are produced by pressure/density variation due to which compration and rarefraction develops.
    2) When we speak, we increase the pressure of air near our mouth and so it is compressed. Due to elasticity in medium, this comprasion expands and converts to rarefraction and thereby, it compresses air near it and thats how a sound wave propogates.
    3) Sound wave can be described as pressure wave, dispacement wave and as density wave.
    4) Pressure waves and density wave are in same phase while displacement wave has a phase difference of 90° with them.
    5) S = Asin(wt - kx)
    ◇P = ◇P. sin(wt - kx + 90°) ◇P.=ABK
    ◇g = ◇g. sin(wt - kx + 90°) ◇g.=AgK
    [ g means row and ◇ means delta]

    Good morning sir, i am a very big fan of your teaching. Sir phase difference between displacement wave and pressure wave is 90 degrees, ok, but which one leads and which one lags, if both are possible, then explain with some example graphs, sir make it as soon as possible.
