Why cannot a sound be heard on the moon?how do astronaut s talk to one

1.	Why cannot a sound be heard on the moon?how do astronaut s talk to one another on the surface of moon?
Answer» No sound can be heard on the moon because there is no air in space. Space is a VACUUM. Astronauts talk to ONE another on the surface of moon through wireless sets that uses radio WAVES. This is because radio waves can travel through vacuum, whereas sound waves cannot travel through vacuum as they require material MEDIUM for their propagation.Hope it helps, please mark as brainliest if it does :)
