Explanation:
Detailed explanation-1: -Space has no air. Since sound waves require a material medium to propagate, therefore, astronauts cannot talk to each other in space.
Detailed explanation-2: -While wearing the current space suits, astronauts wear a Communications Carrier Assembly (CCA), or “Snoopy Cap”-a fabric hat fitted with microphones in the ear area for listening and boom microphones in front of the mouth for speaking.
Detailed explanation-3: -Because there is nothing out in space (like an atmosphere), 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!
