Hence, the wave will last longer. Sound is a mechanical wave and cannot travel through a vacuum.

If the strobe light puts out a flash of light at a frequency of Hz two times the frequency of the tuning forkthen the tuning fork can be observed to be moving in a back and forth motion.

Just as humans have eyes for the detection of light and color, so we are equipped with ears for the detection of sound. Electromagnetic waves do not require a medium in order to transport their energy. Typically, this medium is air, though it could be any material such as water or steel.

From these three similar experiments, we have found out that as more energy is applied to the wave frequency increasesthe wavelength will decrease and vice versa.

Because mechanical waves rely on particle interaction in order to transport their energy, they cannot travel through regions of space that are void of particles. Waves Mechanical Waves Background Mechanical waves are waves which require a medium for propagation since energy is transferred via the motion of the medium.

Transverse waves are waves which vibrate perpendicular to their direction of propagation. Subsequently the disturbance travels through the slinky.

The distance between a subsequent crest and a trough is half of wavelength. Nonetheless, we do not actually visibly detect any vibrations of the tines. Longitudinal wave Longitudinal waves cause the medium to vibrate parallel to the direction of the wave. As seen throughout the three experiments, the more energy that is applied onto the object, the result is much larger amplitude.

As the tines of the tuning forks vibrate back and forth, they begin to disturb surrounding air molecules.

Rayleigh waves, also known as ground roll, are waves that travel as ripples with motion similar to those of waves on the surface of water. The speed of the longitudinal wave is increased in higher index of refraction, due to the closer proximity of the atoms in the medium that is being compressed.

A Love wave is a surface wave having horizontal waves that are shear or transverse to the direction of propagation.

The first coil becomes disturbed and begins to push or pull on the second coil. A sound wave is similar in nature to a slinky wave for a variety of reasons.

In this unit, we will investigate the nature, properties and behaviors of sound waves and apply basic wave principles towards an understanding of music.

The generation and propagation of a sound wave is demonstrated in the animation below. These disturbances are passed on to adjacent air molecules by the mechanism of particle interaction. Some terms to be considered are: Surface wave This type of wave travels along a surface that is between two media.Quick Answer.

Three examples of mechanical waves are sound waves, slinky waves and water waves. Mechanical waves differ from electromagnetic waves because the energy is transferred through another medium, such as the metal in a slinky, rather than through a vacuum, such as light through outer space. Dec 05,  · In this episode we discuss the two major types of mechanical waves and identify their parts.

Examples of each type are also provided. 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.
