Question

electrical devices are used by the astronauts to communicate with each other on the moon why?​

Answer 1

Answer:

electrical devices are used by the astronauts to communicate with each other on the Moon because there is nothing out in the sound waves from one astronaut's whistling can't travel over to the other astronaut's ears. That's why the astronauts use radios to communicate—even if they're floating in space right next to each other

Answer:

Due to lack of medium, sound can't propagate on lunar surface therefore astronauts use a special type of electrical devices on there helmets which transfers sound waves from their voices into radio waves and transmit it to other astronaut.
