sound doesnt travel through space.
because there is no sound in space and sound cannot travel through vacuum
Sound needs to travel in medium like air, but there is no air in outer space, so sound is unable to travel. So basically sound needs air to travel, if there is no air sound cannot travel, when sound is unable to travel you cannot communicate (talk, speak, etc)
Sound can travel in the solid rocks of the moon but sound can not travel on the surface of the moon because there is no air for the sound to travel in.
Vibration when you talk is caused by air passing through your vocal cords, causing them to rapidly open and close. This vibration creates sound waves that travel through the air and are picked up by your ears as sound.
Sound can travel as long as there is something for it to travel through. This could be a gas (such as air), a liquid (such as water) or a solid (such as a metal). In outer space there is no air for the sound to travel though, so astronauts can not talk with each other unless they use a radio. Radio waves and light waves can travel through space, that is why we are able to receive light from the sun. Source: www.examville.com
Sound requires a medium to travel
Sound can travel on the moon because there is no atmosphere. Space is a vacuum that does not allow sound to travel.
Sound wave do not travel through vaccum as it need medium to travel.
On the moon, there is no atmosphere to carry sound waves, so there is no medium for the sound to travel through and reach the other person's ears. As a result, sound cannot propagate in the same way it does on Earth, and communication through sound would not be possible between two individuals on the moon.
sound needs a material medium to travel. Sound can travel by compression and rarefactions.attma
sound is simply the vibration of particle if you talk then your vocal cords vibrate making sound an ear detects sound using a bone witch shakes a part of your ear with sensitive hair the hair then sends the sound as an electric signal down your nerves
