What moves backwards and forwards in sound?
The atoms of the particular medium in which the sound is produced moves backward and forwards in sound.
The medium in which speed of sound maximum?
The speed of sound is dependent on pressure and the density of the medium. velocity = square root of ( change in pressure / change in density ) In any given medium, both the pressure and density vary dramatically compared to air. So the effect is that the speed of sound is increased in materials that have a higher ratio of pressure to density. Some examples are: Air at 0 degrees C, absolute pressure 1 bar : 343 m/s Water at 0 degrees C : 1435 m/s Although the water is greater density than air, the pressure is much greater so sound travels faster. Diamond permits speed of sound at 12000 m/s
How do sounds made and how do they travel?
sounds are made by vibrations when air molecules move either back or forth
What is required for a sound wave to be reflected?
It has to have a hard surface to bounce off of. :)Apex Not necessarily. The reflector is the surface of a medium of greater density than that through which the incident sound travels, and it can be the surface of water, or a density-boundary caused by sharp temperature or salinity differences in the sea.
Speed of sound in coffee?
1497 metres per second is the speed of sound in water at 25 degrees C. The speed in coffee will vary slightly with the density but will not be much different.
When a sound moves towards you what happens to the wave speed?
It stays the same.
When a sound source moves towards you what happens to the wave?
It stays the same.
What happens to the pitch as a sound source moves closer to listener?
As a sound source moves closer to a listener, the pitch of the sound will increase. This effect is known as the Doppler effect, where the perceived frequency of a sound wave increases as the source moves towards the listener.
What happens when the pitch of a sound seems to changeas the sound source moves toward an observer?
In that situation, what happens is that the pitch of sound seems to change as the sound source moves radially with respect to the observer. When the source approaches the observer, the pitch rises, whereas if the source should recede, then the pitch would fall.
An ambulance siren speeds away from you. what happens to the pitch of the sound?
As the ambulance moves away from you, the pitch of the sound will decrease. This is because the sound waves get stretched out due to the Doppler effect, causing the frequency of the sound waves to decrease as the source moves away.
The low2 point of a sound wave the rarefractions where the lowest air pressure occurs?
density
What happens to the speed of a mechanical wave when it moves from a gas to a solid?
The speed of a mechanical wave typically increases when it moves from a gas to a solid medium. This is because sound waves travel faster in solids due to the higher density and greater stiffness of the materials, which allows for quicker transmission of the wave energy.
What happens to the wavelength of the sound as it moves away from you?
As sound moves away from you, the wavelength stays the same but the frequency decreases, causing the pitch to sound lower. This is because sound waves spread out as they travel and the distance between wave peaks increases, resulting in a longer wavelength.
Does sound move?
yes sound does moves the sound moves in waves
How does does the Doppler effect relate to a passing siren?
Sound is a wave; the sound wave is distorted by the Doppler effect. You can clearly hear the change in pitch, from the point where the car approaches you, to the point where it moves away from you.
Why does the energy of a sound decrease over time?
Sound travels spherically from where it was made. If energy is to be conserved a sphere of an earlier point will have a higher flux density than one from a later point.
What happens to the air particles above the drumhead when the drumhead moves downward?
When the drumhead moves downward, it compresses the air particles above it, increasing their pressure and density. This compression creates a wave of compressed air particles that propagates outward in all directions as a sound wave.
