Answer 1

The correct answer is Mechanical waves

Key Points

Mechanical waves are waves that require a medium to travel through.
They propagate by the oscillation of particles in the medium, transferring energy from one particle to the next.
Examples of mechanical waves include sound waves, water waves, and seismic waves.
Sound waves specifically are longitudinal mechanical waves where the particle displacement is parallel to the direction of wave propagation.
Unlike electromagnetic waves, mechanical waves cannot travel through a vacuum.

Additional Information

Electromagnetic waves do not require a medium to travel and can propagate through a vacuum.
Examples of electromagnetic waves include light, radio waves, and microwaves.
Mechanical waves can be classified into two types: longitudinal and transverse waves.
In longitudinal waves, particle displacement is parallel to the direction of wave propagation, while in transverse waves, particle displacement is perpendicular.
Understanding the nature of mechanical waves is crucial in various fields such as acoustics, seismology, and oceanography.
