What happens to sound when it hits a vacuum? Because there is nothing for the sound wave to vibrate against, what happens to the energy?
A vacuum is a space that is completely devoid of matter, including air molecules. It is a region with very low pressure compared to its surrounding environment.
Sound cannot travel through a vacuum because it requires a medium, such as air or water, to propagate. In a vacuum, there is no medium for sound waves to travel through, so they cannot be heard.
Yes, energy can be transferred through a vacuum via electromagnetic radiation, such as light and heat. This type of energy does not require a medium to propagate and can travel through a vacuum.
In a vacuum, sound energy dissipates quickly due to the absence of a medium to carry the sound waves. As a result, sound energy is unable to be transmitted over long distances in a vacuum.
Yes, there is one known exception to sound not being able to travel through a vacuum: gravitational waves. These waves, which are produced by massive bodies in space, can propagate through a vacuum and have been detected by specialized instruments on Earth.
