  1. Sensei if we keep a fan perpendicular to a radio at it's left side then will their be any problem while hearing its sound as it is drifting the air particles away?

    2. i think since the sound's medium which were the air particles drifted away so it will be hard for us to hear, as the fan disturbed the air particles

    3. You are thinking right "Agrima" :) Fan will create a pressure difference and this pressure difference will get superimposed with the pressure difference created by the speaker of the radio resulting in distortion.

  3. Sir,
    I'm Shubham Agarwal, IX-C
    Question: When reverberation occurs then the (various) sound waves are formed and get struck to an object and rebounce to some other object. So sir my question is that when two sound waves got struck with each other then what will happen?
