sound waves bounce off of walls. they need air to travel.
Sound waves need a medium in order to propogate. Light waves can travel without a medium. The speed of light is 3*108m/s.
The sound not travel through vacuum because sound need a medium to travel.
Sound wave do not travel through vaccum as it need medium to travel.
Yes they do need particles to travel through!

An atmosphere. Sound cannot travel in a vacuum.
First of all, it needs a source. But mostly, it needs vibrations. Depending on how strong the vibrations are determine how long the sound wave will travel.

A sound wave is essentially fast changing sound pressure. Longitudinal sound waves need a medium to travel through in order to exist.
hoe does sound travel im at school and i need to know!

Sound can't be heard on the moon because sound need a medium to travel and particles to collide each other in order to travel. since in a vaccum (space) you do not have air, meaning no particles, sound can't be heard on the moon.
