The Moon has no atmosphere, only vacuum. There is nothing for the sound waves to travel in.
Sound is a compression/rarefaction wave in a material, such as air. There is no such thing on the moon.
Because there's no air or other form of atmosphere. Sound need some sort of medium to travel through.
Because there's no air ! They have to communicate by radio.
Sound waves travel via vibrating molecules in air or other materials (water for example). On the Moon there is no atmosphere and as such nothing for sound waves to travel in.
There is nothing to hear in space and on the moon you are too far away to hear anything from earth the scientific reason is that sound moves and bounces to our ears with gravity but because there is no gravity in space it is impossible for sounds to reach us, they simply float away
They wouldn't be able to talk with there helmets off
Sure. When it's on the opposite side of the Earth, for example.
you cant you cant you cant
material medium is necessory to propogation of sound .on the moon their is vacuum that is no air ,therefore sound can not be propogate on the moon.thus two people on the moon can not hear echo other.
Because the gravity of the SUN and the MOON are pulling at 90 degrees to each other and not with each other.
can you haer the moon
you cant marry karen,only the other girls!! :( sorry
