Question

Can we talk in the moon as on earth? If, not how astronauts can communicate with each other at moon?

Answer 1

1. Sound is a longitudinal type of a wave which requires a medium for its propagation.
2. Sound cannot travel through vacuum.
3. On the moon there is atmosphere present, which means no medium is present in the moon.
4. So sound cannot travel on the moon.
5. Astronauts can communicate with the help of non-mechanical waves.

We cannot talk on the moon since there is no air present, Astronaut communicate with non-mechanical waves.
