Chapter 16 - Sound Sound waves are longitudinal waves with rarefaction and compression. As an object’s vibration moves toward air it creates a compression As the object moves away from air it creates a partial vacuum (rarefaction) Sound travels faster through solids and liqu...

Sound Waves:Sound waves are mechanical waves that are detected by the observer. The sound waves that can be detected by the human ear are the frequencies between 20 Hz - 20,000 Hz.Answer and Explanation: Yes, sound waves that propagate through fluids are longitudinal waves. Longitudinal waves...
Longitudinal (compression) waves made by vibrating matter Sound Waves 15.2 Sound Waves A sound wave is a wave of alternating high-pressure and low-pressure regions of air. Sound waves need a medium to travel Sound travels faster through denser mediums Does sound travel faster through water or ...
Sound waves can be categorized into two main types: longitudinal waves and transverse waves. Longitudinal waves cause the medium to vibrate parallel to the direction of wave propagation, while transverse waves cause the medium to vibrate perpendicular to the direction of wave propagation. Sound waves...
It has a velocity in air at sea level at 0°C of 331 metres per second (741 miles per hour) and travels as longitudinal waves b. (as modifier): a sound wave. 2. (Broadcasting) (modifier) of or relating to radio as distinguished from television: sound broadcasting; sound radio. 3...
The attenuation of longitudinal soundwaves in high purity tin has been measured in a large, perpendicular magnetic field as well as in the absence of a field. It is shown that such measurements make it possible to investigate the magnitude of the electron-phonon interaction, the electronic mean...
that radiates outward in straight lines in the form of a pressurewave. The effect these waves produce upon the ear is perceived as sound. From the point of view of physics, sound is considered to be the waves of vibratory motion themselves, whether or not they are heard by the human ear...
The sound velocity of a shear wave in a given material is usually one half of a longitudinal and about 1.1 times that of a surface wave. Specific velocities are tabulated in handbooks and are used for calculations to determine the angle transformations. The effect of temperature on sound ...
