How does sound move?
Sound desires a medium like air, water or solids to journey via. When something actions via the air, it disturbs the molecules of fueloline withinside the air round it. The air vibrates or movements returned and forth. This vibration is heard as sound. The more the vibration, the louder the sound. Since sound travels in waves, it receives weaker the in addition it travels. That is why your voice can't be heard past a positive distance. If you placed in extra strength and shout, the sound waves will be more potent and journey similarly in order that your voice may be heard in addition. Sound can't journey thru a vacuum, due to the fact a vacuum is absolutely empty, and has no medium with which to hold the sound wave.
