Question

why sound waves cannot travel in space.

Answer 1

i dont understand??

Answer 2

Sound waves move in air (as we normally think of it). In space, where there is no air, sound waves cannot arise or move, consequently.

Answer 3

They don't travel through space because sound needs a physical material to pass through.

Answer 4

here i like how they explained it here.

Answer 5

To be more precise, soun waves can only move in 'matter', i.e. in air, water or solid materials like tree or metal structures. Astronauts can speak in the spacecraft, though, because there is a supply of air inside the cabin.

Answer 6

thank you you help me with my question. I know the can't move out in space but i didnt know the real reason. Like what was stopping them. Like I'm always seeing a flashing moving star

Answer 7

falling stars are a little different then sound waves(: but your welcome!!!

Answer 8

@digistor they use radios too because electromagnetic waves dont need matter to pass thru(: but yeah your right.

Answer 9

thanks=)

Answer 10

@bngaure - yes, Sinderella focused on sound waves in space. Fortunately, radio signals can move through vacuum, so the astronauts are always connected with 'Mother Earth': They can submit messages or 'talk home' anytime via 'the electromagnetic channel'... and they can always see our sun enlighted Blue Planet... :)

Answer 11

Sound waves are basically compression waves, and for that, you need some sort of medium (e.g. air or water). In space, there isn't anything to compress, so you can't have a compression wave.
