Question
Matter is made up of particles, but outer space is empty – it has no particles at all.
Propose a reason why sound from the Sun can't travel to the Earth.
Solution
Sound needs a medium to travel through, such as air, water, or a solid substance. This is because sound waves are actually energy being transferred through these mediums via the vibration of particles.
In outer space, there is a vacuum, meaning it is largely empty and has no particles. This lack of particles means there is no medium for sound waves to travel through from the Sun to the Earth.
Therefore, even though the Sun is constantly emitting energy and even produces sound waves due to its intense heat and the reactions happening on its surface, these sound waves cannot reach the Earth because they cannot travel through the vacuum of space.
