Why does sounds travel faster in warm air than in cool air?
The average mean speed of the molecules of air is faster in warm air than on cool air. Sound is transferred by collisions of molecules. Therefore sound waves will travel faster on warm air because collisions of molecules of air in warm air is greater.
Why can't sound be heard in a vacuum?
Sound is a compressional wave, and travels from particle to particle, through matter in waves of pressure. When someone speaks, they drive air through their vocal cords, which causes them to vibrate (if there not relaxed). These vibrations generate the compressional waves that are detected by your ears as sound. In a vacuum, such as in empty space, there is no substance for the waves to travel through, so the compressional waves, sound, have no way to reach a listener. Sound is a compression wave, or a pattern of high density areas (compressions) and low density areas(rarefactions). As the density of one area moves back to normal, it throws its abnormality onto an adjacent area, which is how sound moves. If there were no medium to move through, such as in a vacuum, there would be nothing to compress, and, therefore, no way for sound to exist.
How the sound is produced?
by movement or air molecules which you produce from your mouth its basically the vibrations answer by manohar madhavarapu
What will vibration of air molecules produce?
Vibrating gasses, like air, produce longitudinal waves of pressure, some of which can be perceived as sound. If the molecules are ionized, they will also produce electromagnetic radiation.
Which type of wave a sound wave is?
A sound wave is logitudinal because the motion of the medium (air) travels in the same direction as the wave (back and forth).
Why sound does not travel through a vacuum such as in space or on the moon?
The absence of air molecules to transmit and carry sound waves .
What carries sound vibrations?
Most commonly, air molecules do. More appropriately, when air molecules vibrate that is sound. Sometimes, however, other things can carry vibration which the human ear can pick up.Under water there are no large air bubbles to carry sound, but water molecules can carry it just fine; even better than air, in fact (think of whale calls). Glass and wood are also excellent conductors of sound vibrations (think of how loud it would be if you had your ear up to a door when someone knocked on it).
Why does sound travel through the air?
Sounds vibrate the air molecules, when the vibrating molecules reach your ear, you ear the sound, there are no molecules in space, thus no sound in space
The constant motion of air molecules cause?
air pressure
What wave propety allows sound waves to travel around corners?
In a perfect system Energy Waves would not travel around corners unless reflected off of something. In the case of Sound the medium of travel is the Air. The Wave is "Reflected" off of air molecules and 'travels around the corner. The motion of the air molecules 'reproduces' the sound waves' travel.
What is air motion rate?
Bulk air motion is called "wind speed". Motion of individual molecules in air is covered by temperature and the "kinetic theory of gases".
Describe what must happen to make a sound?
sound is simply the vibration of air molecules. so, sound occurs whenever air molecules are vibrated. but in order for us as humans to hear that sound, the air molecules have to vibrate within a certain frequency range
What is used to transmit sound to great distance?
A vacuum cannot carry sound. Sound waves need a medium for transportation; usually it is air, but sound can travel through liquids or solids, too.Sound is carried usually by air, but it can also be transferred through liquids and solids. A vaccum, like space, has no molecules or atoms to carry or transfer sound through, therefore no sound is heard.
Air molecules speed up the movement of objects in motion?
The friction (with the air molecules) would slow it down.
Air pressure is caused by?
air pressure is caused by the constant motion of air molecules
Would sound travel faster in warm air or cold air why?
The sound travel faster in warm air because the average mean speed of the molecules of air is faster in warm air than on cool air. Sound is transferred by collisions of molecules. Therefore sound waves will travel faster on warm air because collisions of molecules of air in warm air is greater.
Does sound waves make air molecules vibrate?
vibrations make air molecules move
