Which accurately displays the characteristics of mechanical waves?
1. Mechanical waves require a medium to propagate through. They cannot travel through vacuum.
2. Mechanical waves transfer energy from one point to another by the oscillation or vibration of particles in the medium.
3. Mechanical waves can be transverse or longitudinal in nature.
4. Mechanical waves possess properties such as amplitude, wavelength, frequency, and velocity.
5. Examples of mechanical waves include sound waves, water waves, seismic waves, and waves on a string.
