Vacuum
Solid
Liquid
Gas
Answer is Right!
Answer is Wrong!
The correct answer is: A. Vacuum
Longitudinal waves are waves in which the particles of the medium vibrate in the same direction as the wave is traveling. They can travel through solids, liquids, and gases. However, they cannot travel through a vacuum.
A vacuum is a space that is completely empty of matter. There are no particles in a vacuum to vibrate, so there can be no longitudinal waves.
The other options are incorrect because they are all media that can support longitudinal waves.
- Solids are made up of particles that are close together and can vibrate in the same direction as the wave is traveling. This allows longitudinal waves to travel through solids.
- Liquids are made up of particles that are close together but can move around more than the particles in a solid. This allows longitudinal waves to travel through liquids, but they are not as fast as they are in solids.
- Gases are made up of particles that are far apart and can move around very easily. This makes it difficult for longitudinal waves to travel through gases, but they can still travel through gases if the wave is strong enough.
