If we (humans) and light can travel freely through the vacuum of space, then why does sound need a medium to travel through something and can’t travel in space?
In: Physics
Sound isn’t a particle. Sound is the vibration of molecules that are already there in the air. That’s why sound can’t travel in space, because in space, there isn’t any matter/molecules to make any vibrations. Sound is really kind of cool sense that we have. We hear it as sound, but really we’re interpreting the vibration of the molecules in the atmosphere around us. That’s why sound travels slower than light. Because light is an actual particle, called photons. It travels well…… at the speed of light. Sound is like, comparable to having a gush of air hit you. Similar but not really, but just trying to explain like you’re 5 😉
