Q.06
A physics professor demonstrates the Doppler effect by tying a 600 Hz sound generator to a 1.0-m-long rope and whirling it around her head in a horizontal circle at 100 rpm. What are the highest and lowest frequencies heard by a student in the classroom? Assume the room temperature is 20°C.
While driving down the road, you spot a friend standing on the sidewalk.
You honk your horn at them while driving 60 km/h. Your horn emits a
frequency of 330 Hz.
V sound =
: 343 m/s
a. What frequency does your friend hear as you approach? 347 Hz
b. What frequency does your friend hear after you pass by? 315 Hz
