Answer» The Moon has no tangible atmosphere – at its surface, it is a near vacuum. Sound waves are pressure waves that propagate by vibrating the molecules of a medium, such as air or water. In a vacuum, there is nothing to vibrate, and thus no propagation. When we speak, we are using our mouths to create vibrations in the air in our mouth. That air passes the vibration to the air just outside our mouth, which passes the vibration to the air next to it, and so on, until it reaches the air in our ears, which pass the vibration to our ear drums. Electromagnetic waves can travel through the vacuum of space. They don’t need a medium other than space itself. So, astronauts on the Moon’s surface would talk to each other using radio. |
