Question

How can you show that sound cannot travel through vacuum?

Answer 1

We can prove that the sound require medium to trave by following activity.:-

A ringing bell is placed inside the airtight glass jar Containing air. We can hear the sound of ringing bell clearly. Thus, when air is present in glass jar, sound can travel through it and reaches our ear..

Now,

A ringing electric bell is placed inside the glass jar over the vaccum pump. Air is gradually removed by the vaccum pump in the jar. As more and more air is removed to the glass jar then the sound become father and father. When all the air is removed from the glass jar, no sound can be heard at all. Thus, when the vaccum is created in the glass jar then the sound of ringing bell placed inside it cannot be heard. This show sound can't be travel through vaccum..

Answer 2

Answer:

Sound waves are mechanical waves. Unlike electromagnetic waves, they require a medium to propagate.

Sound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work on it.
