The table that accurately displays the characteristics of mechanical waves is the third one. Here is an explanation of each property:
- They can be transverse. - Yes: Mechanical waves can be transverse (e.g., waves on a string).
- They can be longitudinal. - Yes: Mechanical waves can be longitudinal (e.g., sound waves).
- They can propagate in a vacuum. - No: Mechanical waves require a medium (like air, water, or solids) to propagate; they cannot travel through a vacuum.
- They can propagate in a physical medium. - Yes: Mechanical waves need a physical medium to travel through.
- They are composed of high-energy particles. - No: It is not accurate to say that mechanical waves are composed of high energy particles; they involve the oscillation of particles in the medium, which can occur at various energy levels.
- They transfer energy from particle to particle. - Yes: Mechanical waves transfer energy through the oscillation and interaction of particles in the medium.
Therefore, the third table is correct:
| Property | Does a mechanical wave possess this property? | |-----------------------------------------------------------|------------------------------------------------| | They can be transverse. | Yes | | They can be longitudinal. | Yes | | They can propagate in a vacuum | No | | They can propagate in a physical medium | Yes | | They are composed of high energy particles | No | | They transfer energy from particle to particle. | Yes |
