Direct students to label a crest, a trough, a compression, a rarefaction and wavelengths, as well as the amplitude on the transverse wave. Challenge Some opera singers have voices so powerful they ...

If a compression and a rarefaction overlap, they can cancel and make just normal plain air. If two compressions meet at the same time (and place) they can make a region with even higher pressure ...

Longitudinal waves show areas of compression and rarefaction: compressions are regions of high pressure due to particles being close together. rarefactions are regions of low pressure due to ...

Your vocal cords vibrate 100-1,000 times a second. You can feel them vibrate if you lightly touch a finger on your throat when you speak. The localized compression of the air is called condensation.

This is how noise-canceling headphones work—they produce a sound wave that resembles the wave responsible for the unwanted sound, but with the original phases of rarefaction and compression flipped.

This is accomplished by venting the breech through an expansion nozzle during the firing cycle. If the timing is done correctly, the rarefaction wave from the venting will not reach the projectile ...

Sound waves are propagating disturbances of compression and rarefaction in fluid media 6.When a sound wave encounters a material slab or 'particle' with a different density and/or compressibility ...
