Two speakers are driven by the same oscillator with frequency of \( 200 \mathrm{~Hz} \). They are located \( 4 \mathrm{~m} \) apart on a vertical pole. A man walks straight towards the lower speaker in a direction perpendicular to the pole, as shown in figure.https://bit.ly/YTAI_PWAP https://www.pw.live
