![]() Since the propagation of seismic waves requires a rigid medium, they are classified under the category of mechanical waves. Seismic waves are waves produced due to the movement of the tectonic plates of the earth or because of an earthquake. The player then moves the rope up and down, causing it to form crests and troughs, thereby displaying the action of a transverse mechanical wave. The leisure end of the rope is handed over to the player. To observe mechanical waves in a battle rope, one end of the rope is tied to a rigid holder, while the other end is kept idle. The battle rope is common exercise equipment in a gym or in an athletic training centre. Hence, the stadium wave is a classic example of mechanical wave. The audience present in the stadium acts as a medium for the wave to travel from one location to the other. Hence, the waves produced by a spring or a slinky are known as longitudinal mechanical waves.Ī stadium wave or the Mexican wave is formed when a group of people pull their arms up rhythmically one after another. The compressions and rarefactions formed by a deformed spring can be easily observed. When a push or a pull force is applied to one end of a spring or a slinky, keeping its opposite end stable, its particles tend to vibrate back and forth in a direction parallel to the movement of the spring. Hence, the ocean and sea waves are yet another example of transverse mechanical waves in real life. The crests and troughs of such waves are easily visible. Ultrasonic and infrasonic sound waves are inaudible to humans, but they are also an example of mechanical waves.ĭue to the action of the gravitational force of the moon, the earth, and the sun, the water present in the seas or oceans receives a pull force, leading to the formation of a wave. In other words, the sound is incapable of travelling through a vacuum. This is because a sound wave necessarily requires a medium to propagate from one location to the other. Sound waves are a prominent example of mechanical waves. Longitudinal waves are also known as i-waves.Įxamples of Mechanical Waves 1. ![]() Compressions demonstrate the region of maximum pressure and density, while rarefaction is the region of minimum pressure and density. Longitudinal waves travel in the form of compression and rarefaction. This implies that the particles of the medium vibrate to and fro. They are also known as t-waves.Ī mechanical wave is said to be longitudinal if the particles of the medium tend to oscillate in a direction parallel to the direction of propagation of the wave. The maximum displacement formed by a transverse wave in the upward direction is known as a crest, whereas the maximum displacement formed by a transverse wave in the downward direction is known as a trough. In other words, the particle motion and the wave motion of a transverse wave are aligned perpendicular to each other. This implies that the particles of the medium vibrate up and down. Transverse WavesĪ mechanical wave is said to be transverse if the particles of the medium tend to oscillate in a direction perpendicular to the direction of propagation of the wave. ![]() Depending on the direction of wave propagation, mechanical waves can be classified into two broad categories, namely, transverse waves and longitudinal waves. ![]()
