    For people writing jee (even for mains) learn the following topics not included in this series :
    1) loudness level
    2) Resonance tube / resonance column
    3) Doppler effect for reflected sound (it is very similar, just solve one question (may include beats in it)
    4)Doppler effect when S & O are not moving along a line (basically ignore component perpendicular to direction of sound, would be better to attempt a question with a video explanation)
    5) sonometer wire
    6) end correction [for closed/open organ pipe + resonance tube]

    Doppler effect is beautiful! It literally tells us that there’s no absolute frequency as everything is relative, just like newton said that there’s no absolute rest. This is so similar to the time dilation equations by Einstein.

  • @SujalJani_IIT_Goa
    @SujalJani_IIT_Goa 3 года назад +11

    Summary of today's lecture :
    1) Due to relative motion between source and observer, apparent frequency is not same as orignal frequency.
    F = V/ Lamda
    2) When observer moves towards stationary source, velocity of wave wrt observer changes(relative velocity) due to which F app. changes.
    3) When source is moving towards stationary observer, velocity doesnot changes but wavelenth of wave changes, as ,
    After emitting a wave (or say a wavefront/wavelet), source moves forward/backward and than it emits second wave and so distance between two consecutive waves changes and thus lamda changes and thats why Orignal frequency also changes, for both, observer and source.
    4) Fo = Fs [ (C +/- Vo) / (C -/+ Vs) ]
