Why Do astronauts cannot hear each other on the moon?

Astronauts cannot hear each other on the moon due to the lack of air and atmosphere, which are necessary for sound to travel. Sound waves need a medium to propagate, and in the vacuum of space, there is no medium for sound to travel through. While astronauts can communicate through radios inside their helmets, they cannot rely on sound to transmit through the lunar environment.

When two men talk on the moon they cannot hear each other why?

On the moon, there is no atmosphere to carry sound waves, so there is no medium for the sound to travel through and reach the other person's ears. As a result, sound cannot propagate in the same way it does on Earth, and communication through sound would not be possible between two individuals on the moon.


How can you talk on the moon?

Suppose you and your friend are on moon will you be able to hear any sound produced by your friend?

No, sound cannot travel through the vacuum of space, so you would not be able to hear any sound your friend makes on the moon. Sound requires a medium, such as air, to travel through, and the moon does not have an atmosphere like Earth.


Why can't sounds be heard on the moon?

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.
