Sound consists of energy moving the molecules of a medium (air, water, rock), with a certain strength (amplitude) and vibration time (frequency). When a person speaks, the vibration from his voice pushes against the air molecules, which push against other air molecules, producing a widening wave front of molecular motion. The modulated energy of the vibration may eventually reach another person's ear. There the repeated impacts by the molecules are translated into nerve impulses, which the brain can interpret as vocal sounds.

Because sound tends to spread out in all directions, there can be barriers directly between two people and yet one's voice may still be heard by the other.

Is sound a particle or a wave?

Sound is a wave, not a particle. Sound waves are created by vibrations and travel through a medium, such as air or water, to carry sound from one place to another.


How can sound refract in different mediums?

Sound can refract in different mediums due to changes in the speed of sound waves as they travel from one medium to another. When sound waves enter a new medium at an angle, they can change direction and bend, causing the sound to refract. This bending occurs because sound waves travel at different speeds in different mediums, which causes them to change direction as they move from one medium to another.


What is necessary for sound to travel from one place to another?

Sound requires a medium through which it can travel, such as air, water, or solid materials. When an object vibrates, it causes the particles in the medium to vibrate, creating sound waves that travel through the medium. The speed of sound in a medium depends on its properties, such as density and elasticity.


Do sound waves need a material to travel in?

sound wave need material becuse sound wave formed by compresion and rarefaction


How does sound get from one place to another?

Sound travels from one place to another as a result of vibrations. When an object or a source of sound such as a speaker vibrates, it creates compressions and rarefactions in the surrounding medium, usually air. These compressions and rarefactions are propagated as waves, which travel through the air and reach our ears, allowing us to perceive the sound.

Can sound waves travel in a vacuum.?

Sound cannot travel through a vacumNo. Sound waves can not travel in a vacuum. Sound works by having molecules of air knock against other molecules of air. Then those molecules knock against other molecules. The energy is transferred from one molecule to the next. These molecules we hear transferring energy from one to another we hear as sound. Where molecules can not transfer energy to another molecule, such as in a vacuum, sound can not exist.
