It Can it needs a medium to travel
light can travel through a vacuum whereas sound cant
Why cant sound travel through empty space
Sound is something that cannot be seen, touched, or felt but can be heard. It is a result of vibrations transmitted through a medium, such as air or water, that are then detected by our ears. Sound waves travel through the air and cause our eardrums to vibrate, allowing us to perceive sound.
Because sound needs a material medium to travel through, and there's no material between us and the sun. We can understand how important it is to have air or something for sound to travel through when we see videos of Apollo astronauts on the moon, where there's no air. They may be only a few feet apart, but still they can only communicate by radio. Without air, sound doesn't work at all.
light cant travel through opague materials, or anything you cant see through.
No medium to carry the sound energy.
light can travel through a vacuum whereas sound cant
Sound (and vibration) are a wave system of sequential compressions and rarefactions of a material. These waves are mechanical and do need a substance through which to travel. They cannot travel through a vacuum.
Why cant sound travel through empty space
Because there's no air or other form of atmosphere. Sound need some sort of medium to travel through.
There is no air for sound to travel through.
sound can't travel through a vacuum. or a place without air.
sound cant travel on an asteroid because it has no atmosphere. it could travel through it.
light can but sound cant as there is no air
there is no air in a vaccum. and sound needs air for the sound waves to travel through.
Sound, unlike light, needs a medium through which to travel. Sound relies on vibrating molecules or particles. Sound can travel through air at about 3 km/s as it vibrates particles and then the neighbouring particles etc. but it can travel much faster through steel because the particles are much more tightly packed.In outer space there are not enough particles to vibrate, no neighbouring particles for the very few particles that are there. No particles means that there is no sound.
Sounds requires a medium to travel through. An example is air. You've also heard sound travel through water and solid objects like wood. In the past it was often thought that no medium exists in space. However, in current astronomy and astrophysics it is thought that dark matter is the medium by which sound can and does travel about space. Due to the atoms being so spread out though, the human ear would not be capable of detecting the sound waves.
