Question

7 why can sound not travel through a vacuum? a the vacuum does not have any particles that are required to transport the sound waves. b the vacuum does not have enough particles to transport the sound waves. c the vacuum has too many particles that are packed too closely to transport sound waves. d the vacuum has the incorrect type of particles to transport sound waves.

Explanation:

Sound is a mechanical wave that requires a medium (particles) to travel. A vacuum is an empty space with no particles, so sound cannot propagate through it.

Answer:

A. The vacuum does not have any particles that are required to transport the sound waves.
