A table is revolving on its axis at 5 revolutions per second. A sound source of frequency 1000 Hz is fixed on the table at 70 cm from the axis. The minimum frequency heard by a listener standing at a distance from the table will be nearly (speed of sound = 352 m/s)
detailed solution
Correct option is C
For source vs=rω=0.70×2π×5=22 m/sec Minimum frequency is heard when the source is receding the man. It is given by nmin=nvv+vs=1000×352352+22=941 HzTalk to our academic expert!
