Question

why sound cannot be heard on the moon?​

Answer 1

Answer:

The air here on Earth allows sound waves to move from one point to another (sound can also move through water, steel, earth, etc… it just requires that particles/atoms/molecules are touching one another). However, the Moon is in space, and space is mostly a vacuum (there are always some atoms floating around, but they are VERY far apart and don’t interact with one another). Thus there is no sound on the Moon.

Answer 2

Answer:

because there is no atmosphere

Step-by-step explanation:

in the space , there is no atmosphere. it is a vacuum space .

sound is a wave and need a medium to travel as it propagated due to vibrations

since there are no molecules in space to cause collision, sound can't be transmitted
