Question

How do astronauts communicate on the surface of the moon?

Answer 1

we knew that sound cannot pass in space.So they use radio waves to talk or communicate between them.

Answer 2

As You Know

SOUND NEED A MEDIUM TO TRAVEL

MOON has no medium

so ASTRONAUTS helmet have a device to convert their VOCAL VOICE into RADIO signals so that the Another AstroBoy can hear him by RECEIVER

Hope you understand
