18 Μαρ 2012 · Sound waves are longitudinal waves that require a medium. The amplitude of a wave determines its volume or loudness, while frequency determines its pitch or how high or low it is. Higher frequencies have smaller wavelengths. The human ear can detect sounds between 20 Hz and 20 kHz.
7 Μαρ 2017 · Sound is a form of energy created by vibrations that travel through matter as longitudinal waves. When an object vibrates, it causes the air particles around it to move in a compression and rarefaction pattern that transfers the sound energy.
4 WHAT IS SOUND? Sound is a form of energy that can be heard and travels in waves. When matter vibrates or moves back and forth very quickly, a sound is made. Sound waves can travel through...
Sound Energy: energy made by objects that vibrate. Vibrate: moving back and forth quickly. Wave: a disturbance that moves through matter or space. Transverse waves: waves that move in and up...
Sound waves are longitudinal waves of compression and rarefaction in which the air molecules move back and forth parallel to the direction of wave travel centered on an average position, resulting in no net movement of the molecules. When these waves strike another object, they cause that object to vibrate by exerting a force on them.
12 Οκτ 2014 · Properties of Sound EQ: How does intensity, loudness, frequency and pitch affect sound waves? Vocabulary • Intensity – the amount of energy an sound wave carries per second through a unit area. Measured in watts per meter squared.
