What is a better carrier if sound?
Air is a better carrier of sound than vacuum. In air, sound waves can travel because air molecules can vibrate and transfer energy. In a vacuum, there are no molecules to transmit sound waves, so sound cannot travel.
What happens to molecules when a sound collides with them?
When a sound wave collides with molecules, it causes them to vibrate and transmit the sound energy through the medium. This vibration is what allows the sound wave to propagate through the material by transferring energy from one molecule to the next.
Does sound travel faster through molecules that are far apart?
No. Sound waves travel fastest through mediums that have tighter or more densely packed molecules. Longitudinal waves need a conductor (i.e. molecule) to transmit sound. The closer the molecules are, the faster a sound wave is able to pass from one to another. Therefore, sound travels fastest through solid mediums (densely packed molecules), then liquids (less densely packed), then gases (least densely packed).
What creates a mechanical sound wave?
A mechanical sound wave is created when an object vibrates, causing the surrounding air molecules to also vibrate and transmit the sound energy through the air.
How does sound waves work to transmit information through the air?
Sound waves transmit information through the air by vibrating molecules in the air, creating changes in air pressure that travel as waves. These waves are detected by our ears and converted into electrical signals that our brain interprets as sound.
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 .

When a sound wave collides with molecules, it causes them to vibrate and transmit the sound energy through the medium. This vibration is what allows the sound wave to propagate through the material by transferring energy from one molecule to the next.
How is light different from sound?
Sound is the vibration of molecules and atoms. Light is made up of things called "light quanta" or "photons." This means that sound cannot travel through a vacuum (there are obviously no molecules or atoms in a vacuum to transmit sound) but light can.
Is the string a better carrier of sound than air?
Yes, solids transmit sound better than gases because their molecules are closer together.
Does sound travel faster through molecules that are far apart?

A region empty of matter throught which sound cannot travel?
A vacuum is a region empty of matter through which sound cannot travel due to the absence of air molecules to transmit the sound waves.
What is the movement of air molecules brought about by a source of vibration?
The movement of air molecules brought about by a source of vibration is known as sound. When an object vibrates, it creates fluctuations in air pressure, causing nearby air molecules to vibrate and transmit sound waves through the air.
Do sound waves make molucules move?
Yes, sound waves transmit energy through a medium by causing molecules to vibrate and move back and forth. This movement is what allows sound to travel through materials such as air, water, or solids.
Without atmosphere would there be sound?
Sound requires a medium, such as air or water, to travel. Without an atmosphere, such as in outer space, there would be no molecules to transmit sound waves, so we would not hear sound in the traditional sense.
