A physics professor demonstrates the Doppler effect by tying \(\mathbb{N T}\) a \(600 \mathrm{~Hz}\) sound generator to a 1.0 -m-long rope and whirling it around her head in a horizontal circle at \(100 \mathrm{rpm}\). What are the highest and lowest frequencies heard by a student in the classroom? Assume the room temperature is \(20^{\circ} \mathrm{C}\).
