Mechanical waves cause oscillations of particles in a solid, liquid or gas and must have a medium to travel through. Once the wave has passed, the medium ends up back in its rest position. For example, after a wave reaches the beach, the sea ends up back where it started.
What are some examples of mechanical waves?
For example, electromagnetic waves such as visible light are not mechanical because they can travel through the vacuum of space to reach us from the sun. Mechanical waves include water waves, sound waves, earthquake waves, and many more. Like all waves, those of the mechanical variety have peaks, or crests, and troughs.

In physics, a mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited.

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.

How do mechanical waves work?
Production of Mechanical Waves. To create a mechanical wave, some initial energy has to be put into it. This is the energy that will then be transferred by the wave. How you provide this energy depends on the medium and type of wave. For example, you could drop a stone in some water to create a water wave.
What are the three types of mechanical waves?
The three types of mechanical waves are transverse, longitudinal, and surface . Surface waves run along the border between two materials; transverse waves are waves in which the vibration is at 90 degrees to the direction of motion; and longitudinal waves occur when the vibration is parallel to the direction of motion.
How do mechanical waves move through a medium?
Mechanical waves move through a medium, and because of that, the nature of that medium affects them. For material to allow a mechanical wave to pass, it has to have some elasticity. Elasticity is how quickly the material returns to its original shape when stretched.
What are the three types of wave propagation?
The three propagation types are: A transverse wave is one that vibrates at 90 degrees to the direction the wave is moving. For example, if you hold a Slinky between two hands and shake it up and down, you'll get a wave that moves along the Slinky, but the vibrations will still be up and down.
What is surface wave?
Last of all, a surface wave is a wave that travels along the boundary between two materials. For example the kind of water wave you most often see, along the top of water, is an example of a surface wave. Surface waves move in similar ways to transverse waves but are a bit more complicated in their behavior.
What type of wave is the primary wave?
The initial earthquake, called the primary wave, is longitudinal, but the aftershock that comes later, the secondary wave, is transverse .
What are the factors that affect the speed of mechanical waves?
Other factors that affect the speed of mechanical waves include: Tension is how much force is being used to stretch a material. A stretched rubber band is under tension, for example. Temperature is a measure of how fast the molecules in a substance are moving.
Who proposed that waves could behave like particles?
It was Einstein who proposed that waves (light) could behave like particles (photons). Heisenberg proposed the first successful quantum theory, but in the terms of the mathematics of matrices — matrix mexhanics. Semester 1 2009 PHYS201 Wave Mechanics 2 / 86. Quantum Mechanics and Wave MechanicsII.

Waves are described using the following terms: 1 Rest position – the undisturbed position of particles or fields when they are not vibrating. 2 Displacement – the distance that a certain point in the medium has moved from its rest position. 3 Peak – the number of waves passing a point each second. The highest point above the rest position. 4 Trough – the lowest point below the rest position. 5 Amplitude – the maximum displacement of a point of a wave from its rest position. 6 Wavelength – distance covered by a full cycle of the wave. Usually measured from peak to peak, or trough to trough. 7 Time period – the time taken for a full cycle of the wave.

Types of Mechanical Waves and How Does Energy Travel in A Mechanical Wave?
- How does energy travel in a mechanical wave? It depends on which type of wave it is. When energy is applied to matter or a medium, the particles within it move causing the transfer of energy. The term propagation describes the traveling of the wave away from its energy source. The pattern of the movement of the particles within a medium transfers this energy in predictabl…
