A traditional speaker produces sound waves when a current is passed through a coil near a magnet. The current varies with the amplitude and frequency of the desired sound. As current passes though the coil, it is attracted to and repelled from the magnet. A cone of paper, plastic, bamboo, or other durable material is attached to the coil, so as the coil makes its movements the paper moves with it. The paper pushes and pulls against the ambient air creating compression sound waves.

∙ 12y agoA sound wave consists of alternating compressions and rarefactions of the air pressure. These variations are at the frequency of the sound wave. A kilohertz sound will have 1000 compressions and 1000 rarefactions per second. In the compression phase, the density of the air will be greater. And the inverse for the rarefactions.

Which one of the following is NOT an example of a compressional wave a wave moving through a coiled spring sound traveling through the air sound traveling through water green light traveling thru air?
Light is an example of an electromagnetic (EM) wave. EM waves are transverse waves, not compressional waves. Sound waves are compressional waves, so both sound traveling through air and water would be compressional. Waves traveling along a coiled spring compress the coils together and spread them apart, so this is also an example of a compressional wave.
What wave is made up of a series of compressions and rarefactions?
it is compressional wave. Compressional waves are a type of sound wave.
How does a compressional wave moves?
for compressional waves, think of a spring. It moves by compressing and contracting. For sinusoidal waves, think of waves on the beach.
Are electromagnetic waves transverse or compressional waves?
They are transverse waves.
compressional wave?
this is the waves of p waves that have same direction of waves
How waves are created and propagate when a tuning fork is struck?
Because of the tuning fork's vibrations. It creates compressional sound waves.
Are sound waves transverse waves or compressional waves Why?
Compressional, gasses can be compressed but cannot be wiggled side to side.
What kind of waves does sound have transverse waves or compression waves?
Sound is a compressional wave.
Why are sound waves compressional waves?
Sound waves are compression waves because the molecules of air are compressed.
Which kind of waves are sound waves?
compressional waves they swerve up and down
What waves causes compressional waves caused by colliding air molecules?
Sound Waves
What and how are compressional waves formed?
by seismographic sound and vibrations
The speaker on your cell phone creates it by vibrating the air to your ear in the form of compression waves?
sound
What is natural sound?
a vibrating body moves to and fro around its rest position and produces compressional waves in the surrounding medium. these compressional waves are called the sound waves which trevles from one place to another.

What is a compressional wave caused by colliding air molecules?
Sound Waves
How do air molecules enable sound to travel from a radio speaker to your ear?
Sounds waves are compressional, and compressional waves are made up of compressions and rarefactions. When the radio speaker pumps sound outward, it forms a compression by pushing the molecules in air together. The compression moves away from the speaker as these molecules collide with other molecules in air. When the sound travels back, a rarefaction is formed where the molecules are farther apart. The air molecules form compressions and rarefactions. Compressions and rarefactions make up compressional waves. A sound wave is a compressional wave.
