Why sound doesnot travel in vacuum medium?

Answer 1

sound can be produced when vibration occurs.

there are no vibrating bodies in space .

so , sound doesn't travel in vaccum medium.

Answer 2

Answer:

In the vacuum of space, there are no (or very, very few) particles to vibrate, so sound cannot travel through this medium. ... Radio waves travel perfectly fine through a vacuum because they are a type of electromagnetic wave (light), and electromagnetic waves do not need a medium to travel through.
