Question

what is the speed of sound on the moon

Answer 1

We all know that in space there is no medium in which sound can travel . There is no solid , no liquid and no gas . So , on moon we cannot hear any sound . Therefore , astronauts communicate to each other by signals or microphones in space even they are more closer ........

Answer 2

In order for sound to propagate from one place to another, it requires a medium or a fluid to move through. The atmospheric air here on Earth allows sound waves to move from one point to another. However, there is practically no atmosphere on the Moon In the moon's atmosphere, there are only 100 molecules per cubic centimeter. In comparison, Earth’s atmosphere has about 100 billion billion molecules per cubic centimeter.

Thus there is no sound on the Moon and the question of speed does not arise.
