Mechanical Waves

Mechanical waves are a type of wave that requires a medium to travel through. The medium can be a solid, liquid, or gas. When a mechanical wave travels through a medium, the particles of the medium vibrate and transfer energy from one particle to the next. There are several types of mechanical waves, including transverse waves, longitudinal waves, and surface waves.

Transverse Waves

Transverse waves are waves in which the particles of the medium move perpendicular to the direction of the wave. An example of a transverse wave is a wave on a string. When you flick a string, the wave travels along the string, and the particles of the string move up and down as the wave passes through.

Longitudinal Waves

Longitudinal waves are waves in which the particles of the medium move parallel to the direction of the wave. An example of a longitudinal wave is a sound wave. When you speak, the sound waves travel through the air, and the air particles move back and forth in the same direction as the wave.

Surface Waves

Surface waves are waves that occur at the boundary between two different mediums, such as water and air. An example of a surface wave is a water wave. When a water wave travels across the surface of the water, the particles at the surface of the water move in a circular motion, creating the wave.
