What is the motion of the air molecules that carry sound?
They rapidly compress and rarefy in the direction of the sound wave as the wave travels.
The part of a sound wave where the molecules are spread apart is called?
compression
What are the characteristics of sound waves?
The characteristics of a sound wave is the Amplitude, Frequency, Wavelength, time period, and velocity. The sound wave itself is a longitudinal wave that shows the rarefactions and compressions of a sound wave.
Increasing the amplitude of a sound wave?
Loudness is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a subjective felt impression and is in some way related to the objective measure of the sound pressure. Neither our ear drums nor the microphone diaphragms can convert acoustic intensity. Therefore only use the sound pressure for measuring. To measure the loudness feeling is a difficult thing. The loudness of 1 sone equals the loudness level of 40 phons (at 1 kHz).
What gives a sound wave its pitch and intensity?
A sound wave's pitch is determined by its frequency; that is its cycles per unit of time. The sound wave's intensity or volume is determined by its amplitude; the maximum crest of a sound wave.
What happens to air molecules as sound travels?
As sound travels, air molecules are compressed and rarefied in a wave-like pattern. When a sound wave passes through a medium like air, the molecules vibrate back and forth in the direction of the wave, transmitting the sound energy. This vibration causes changes in pressure that our ears detect as sound.
What are molecules in the compression part of a sound wave?
Sound waves that are compressed are made of (air) molecules that are more densely concentrated - that is (ie) more molecules are packed into the space of the compressed wave than there are in the (same) space of the surrounding expanded waves.
Where is air compressed in a sound wave?
Air is compressed in a sound wave at the regions of high pressure, known as compressions. These compressions are created by the vibrations of a sound source, which causes air molecules to move closer together. The areas of low pressure, known as rarefactions, occur in between the compressions where air molecules are more spread out.
Why is soundwave can travel to all kinds of matterbut not to a vacuum?
a sound wave is the movement of the molecules of the material, so no molecules no sound wave.
How do air molecules move when a basketball hits a gym surface?
As regards the ones on thie inside, the air atoms and molecules (yes, there are both 'cause air is a mixture of gases) are compressed on the inside of the ball. They are compressed in the area adjacent to the surface that is being compressed, and the compression wave travels across the inside of the ball to the other side and rebounds. Yes, a wave will result from the compression of one side of the ball. And that compression wave moves really fast in there. Like about the speed of sound.
Do sound molecules move perpendicularly to the direction of wave propagation?
Sound molecules traveling through air is an example of a longitudinal wave. It moves parallel to the direction of wave propagation.
In a sound wave what is moving?
the air molecules
What waves consists of compressed and ratified regions of particles that are colliding with one another?
A longitudinal wave such as a sound wave.
What is a sound wave made of?
A sound wave is simply a vibration in the air molecules, or the molecules of some other substance. This vibration propagates as a wave, the energy gets transferred somewhere else.
What is sound wave made up of?
A sound wave is simply a vibration in the air molecules, or the molecules of some other substance. This vibration propagates as a wave, the energy gets transferred somewhere else.
Why are sound waves compressional waves?
Sound waves are compression waves because the molecules of air are compressed.
What is the motion of the air molecules that carry sound?
They rapidly compress and rarefy in the direction of the sound wave as the wave travels.
