You set a tuning fork into vibration at a frequency of 723 Hz and then drop it off the roof of the Physics building where the acceleration due to gravity is 9.80 m/s. Determine how far the tuning fork has fallen when waves of frequency 693 Hz reach the release point? (Take the speed of sound i air to be 343 m/s.) 14.6 x How is the frequency heard by the observer related to the frequency of the source when the source is moving away from the observer? How is the speed of the source related to how far it has fallen? Is it necessary to take into consideration the distance the tuning fork travels, while the sound is traveling from the source to the release point? m Additional Materials Reading
Properties of sound
A sound wave is a mechanical wave (or mechanical vibration) that transit through media such as gas (air), liquid (water), and solid (wood).
Quality Of Sound
A sound or a sound wave is defined as the energy produced due to the vibrations of particles in a medium. When any medium produces a disturbance or vibrations, it causes a movement in the air particles which produces sound waves. Molecules in the air vibrate about a certain average position and create compressions and rarefactions. This is called pitch which is defined as the frequency of sound. The frequency is defined as the number of oscillations in pressure per second.
Categories of Sound Wave
People perceive sound in different ways, like a medico student takes sound as vibration produced by objects reaching the human eardrum. A physicist perceives sound as vibration produced by an object, which produces disturbances in nearby air molecules that travel further. Both of them describe it as vibration generated by an object, the difference is one talks about how it is received and other deals with how it travels and propagates across various mediums.
According to the given data
f=723 Hz
f'=693 Hz
v=343 m/s
