Compression happens during which part of the sound wave?
Compression happens during the part of the sound wave where the air particles are pushed closer together, resulting in an increase in air pressure. This creates a region of higher pressure within the sound wave, causing the compression of the air particles.
What is the pressure of a sound on an ear drum?
The sound pressure wave is travelling down the ear canal, hits the area of the eardrum, which vibrates ... just like a drum! Sound pressure p = force F divided by area A.
If a sound wave speeds up and its frequency does not change what happens to the wavelength?
With the same speed -Apex (1.2.4)
A sound wave has compressions that are very close to each other What is true about this sound wave?
The frequency of this sound wave is very near constant.
What is the result of a reflected sound wave?
The result of a reflected sound wave is obviously an echo.
What happens to a sound wave when it enters a denser medium?
When a sound wave enters a denser medium, its speed decreases and its wavelength also decreases while the frequency remains the same. This causes the sound wave to bend towards the normal line at the boundary between the two media.
What parts in the ear assist in the ability to hear a sound wave from the time the sound enters the ear until it reaches the brain?
The auditory canal to the eardrum then the auditory nerve sends it to the brain for interpretation.
What happens as a sound wave energy decrease?
The sound gets softer.
What happens to the wavelength of a wave as it leaves the air and enters Perspex?
The wavelength of the wave decreases as it enters Perspex due to the change in the speed of the wave, according to Snell's Law. The wave slows down in Perspex, causing the wavelength to shorten.
What happens to the wavelength of a sound wave after reflection?
it changes
How do the wavelength and wave height change as a wave enters shallow water?
As a wave enters shallow water, the wavelength decreases while the wave height increases. This happens because the wave encounters the ocean floor, causing the wave to slow down and compress, resulting in a shorter wavelength and higher wave height.
The amplitude of a sound wave increases. What happens to the sound?
If the amplitude of a sound wave increases, the sound will become louder. This is because amplitude directly correlates with the intensity or volume of the sound.
What happens to the volume of sound as the amplitude get larger?
The greater the amplitude of a sound wave the louder the sound.
What happens to intensity if the amplitude of sound is doubled?
If the amplitude of a sound wave is doubled, the intensity of the sound wave will increase by a factor of four. This is because intensity is proportional to the square of the amplitude of the wave.
How does sound travel from a loud speaker to your ear?
Sound leaves the speaker in the form of a wave, through the air, and enters your year, where the eardrum picks up the vibrations of the wave and sends a signal to your brain which interprets the vibrations as sound.
What happens to the air particles as the sound wave travels through them?
As the sound wave travels through the air, the air particles vibrate back and forth in the direction of the wave, transferring the sound energy.
Compression happens during which part of the sound wave?
Compression happens during the part of the sound wave where the air particles are pushed closer together, resulting in an increase in air pressure. This creates a region of higher pressure within the sound wave, causing the compression of the air particles.
