Doppler Effect: You set a tuning fork into vibration at a frequency of 683 Hz and then drop it off the roof of the Physics building...?
You set a tuning fork into vibration at a frequency of 683 Hz and then drop it off the roof of the Physics building where the acceleration due to gravity is 9.80 m/s2. Determine how far the tuning fork has fallen when waves of frequency 659 Hz reach the release point? (Take the speed of sound in air to be 343 m/s.)
