1. If the handle of a vibrating tuning fork is held against a table, the sound of the tuning fork beams louder. Why? O 1. the tuning fork vibrates more when held against the table 2. there is no difference whether the tuning fork is held against the table or not O 3. sound from the tuning fork travels faster on the table than in air O 4. the vibrating tuning fork causes the table to vibrate, which in turn causes more air to vibrate 2. Which of the following tells the relation between wavelength and period of a wave? O 1. the longer the wavelength, the lower the period O 2. wavelength and frequency are completely independent of each other O 3. impossible to determine O 4. the longer the wavelength, the higher the period 3. Balboa Park in San Diego has an outdoor organ. When the air temperature increases, what happens to the fundamental frequency of one of the organ pipes? O 1. decreases 2. stays the same 3. impossible to determine 4. increases O o o o

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.
