Answer 1

The correct answer is Mechanical wave.

Key Points

A sound wave travels through the air by moving air particles in a chain reaction.
When a particle moves out of its equilibrium position, it pushes or pulls neighboring molecules, knocking them out of balance.
As the particles continue to move with each other with mechanical oscillations, the disturbance is propagated throughout the medium.

Additional Information

Tidal wave:
- Tidal waves are frequently recurring waves in shallow water caused by gravitational interactions between the Sun, Moon, and Earth on the ocean.
- The term "tidal wave" is commonly used to refer to a tsunami; however, this reference is incorrect because tsunamis have nothing to do with tides.
Electromagnetic Wave:
- Electromagnetic waves are also known as EM waves.
- Electromagnetic radiation consists of electromagnetic waves produced when an electric field is exposed to a magnetic field.
Surface Wave:
- Surface waves move more slowly through the earth's matter on the planet's surface and are mostly lower in frequency than body waves.
- They are easily distinguished by seismic.
