Question

We cannot hear any sound on the surface of moon . why ??

Answer 1

The air here on Earth allows sound waves to move from one point to another (sound can also move through water, steel, earth, etc… ... Thus there is no sound on the Moon. In empty space, there is no air, and what we call "sound" is actually vibrations in the air.

Answer 2

In vaccum there are no molecules to oscillate for propagating the sound.so sound cannot travel on the moon
