To study the Doppler shift on your own, you take an 84 electronic tone generating device that is set to a frequency of mid- dle C (262 Hz) to a campus wishing well known as "The Abyss." When you intensity level to be 80.0 dB. You then drop the tuner down the hole, listening to its sound as it falls. (a) After the tuner has fallen for 5.50 s, what frequency do you hear? (b) Estimate the time at which you can no longer hear the tuner. hold the device at arm's length (1.0 m), you measure its
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.
