Can sound travel through a vacuum?

Sound is a form of energy that travels in waves through a medium such as air, water, or solids. However, in a vacuum, there is no medium for the sound waves to travel through. Therefore, sound cannot travel through a vacuum.

Explanation

Sound waves require a medium
Sound waves are mechanical waves that require a medium to travel through. In a vacuum, there is no medium present for the sound waves to propagate. As a result, sound cannot travel through a vacuum.

Vacuum is a perfect insulator
A vacuum is a space devoid of matter, including air or any other medium. This absence of particles means there are no molecules to carry the sound waves. As a result, sound waves cannot travel through a vacuum as there is no medium for them to move through.

Examples of vacuum
Examples of vacuums include outer space and the inside of a sealed container from which air has been removed. In these environments, sound cannot travel due to the lack of a medium to carry the waves.

Conclusion

In conclusion, sound cannot travel through a vacuum because sound waves require a medium to propagate. Without a medium such as air, water, or solids, sound waves are unable to travel and therefore cannot be heard in a vacuum.
