The part of a sound wave where the molecules are spread apart is called?
compression
How does sound travel from instruments to your ears?
Sound creates waves in a material- compression waves. These waves are transmitted through the atoms/molecules in the material to the receiver. The denser a material is, the more effectively sound may travel; this is because the sound waves are transmitted more easily through the tightly packed molecules.
Adding external protrusions to a wing (such as fuel pods water tanks and missiles) would be useful but what could one drawback be?
It can weaken the wing, it creates additional drag, and will produce a larger radar reflection.
How do the particles of energy in a longitudinal wave move?
In a longitudinal wave, the particles do not move with the wave. The particle movement is parallel to the direction of the wave propagation. This means that the particles move left and right which in turn makes the other particles start to oscillate. This creates a wave. longitudinal pressure waves are also known as sound waves.
What is the difference between sound waves and electromagetic?
Sound waves requires a medium, electromagnetic waves do not. Sound waves are longitudinal waves, electromagnetic waves are transverse waves. Sound waves Travels at approx. 330m/s in air, electromagnetic waves travel at approx. 3 x 10^8 m/s.
What do the combination of a compression and a rarefaction create?
A compression and a rarefaction create a sound wave. In a compression, air molecules are pushed closer together, creating a region of high pressure. In a rarefaction, air molecules are spread out, creating a region of low pressure. This alternation between compressions and rarefactions forms the basis of a sound wave.
Does Rarefaction refer to the compression of air molecules?
No, rarefaction is the reduction in density of a gas or fluid, while compression refers to the increase in density. Rarefaction occurs when particles are spread apart, leading to a decrease in pressure and density.
What is the differ between compression and rarefaction in sound wave?
Compression refers to the region in a sound wave where air molecules are pushed closer together, resulting in higher pressure. Rarefaction, on the other hand, is the region where air molecules are spread farther apart, leading to lower pressure. Together, compression and rarefaction create the alternating pattern of high and low pressure zones in a sound wave.
What is the relative spacing of molecules as they are affected by compression and rarefaction?
Compression decreases the spacing between molecules, making them closer together. Rarefaction increases the spacing between molecules, causing them to move further apart. This cycle occurs in a repeating pattern in a sound wave.
What is the crowding together of molecules called?
a compression wave is the crowding of molecules a rarefaction is spread apart molecules
Which part of sound wave has molecules that are tightly packed together?
The compression or crest of a sound wave has molecules that are tightly packed together, which leads to higher pressure and increased density compared to the rarefaction part of the wave.
What is the difference between compression and rarefaction?
Compression is the phase of a sound wave where molecules are pushed together, resulting in an increase in pressure. Rarefaction is the phase where molecules are spread apart, causing a decrease in pressure. Together, these two phases create the waveform of a sound wave.
What is a dense zone of moleculesproduced by a sound wave?
It is referred to as a compression. The non-dense zone with few molecules is referred to as a rarefaction.
True or false A rarefaction is a region in the medium in which molecules are?
True. A rarefaction is a region in the medium where molecules are spread farther apart, leading to a decrease in density. This occurs in a longitudinal wave when the particles temporarily move apart.
Is rarefaction a high pressure area of tightly packed molecules?
No, rarefaction is the opposite of a high pressure area. It is a low pressure area where molecules are spaced further apart. This occurs in a sound wave when the air molecules are spread out, creating areas of decreased pressure.
How do crest and trough relate to compression and rarefaction?
Crest corresponds to compression, where air molecules are tightly packed together, leading to a peak in pressure. Trough corresponds to rarefaction, where air molecules are spread further apart, causing a decrease in pressure. These variations in pressure create the wave-like pattern of sound waves.
How are rarefaction and compression related to sound?
Rarefaction and compression are related to sound waves as they describe the regions of low and high pressure, respectively, created by the oscillation of air molecules as sound passes through a medium. In a sound wave, rarefactions are areas of decreased air pressure where air molecules are spread out, while compressions are areas of increased air pressure where air molecules are closer together. The alternation of rarefactions and compressions creates the characteristic waveform of a sound wave.
