# Report about mechanical waves

Electromagnetic waves are waves that have an electric and magnetic nature and are capable of traveling through a vacuum. Sound is considered a longitudinal wave. 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.

Longitudinal wave Longitudinal waves cause the medium to vibrate parallel to the direction of the wave. A longitudinal wave is a wave in which its particles vibrate parallel to their direction of propagation. With the increase in energy applied, the other result will also be in a higher frequency.

Just as humans have eyes for the detection of light and color, so we are equipped with ears for the detection of sound. An example of a surface wave would be waves in a pool, or in an ocean, lake, or any other type of water body. This push or pull on the second coil will displace the second coil from its equilibrium position.

It consists of multiple compressions and rarefactions. Many Physics demonstration tuning forks are mounted on a sound box. This concept is often demonstrated by the placement of a vibrating tuning fork against the glass panel of an overhead projector or on the wooden door of a cabinet.

The wavelength is the distance from crest to crest or from trough to trough. This feature of mechanical waves is often demonstrated in a Physics class. The disturbance could be created by the vibrating vocal cords of a person, the vibrating string and soundboard of a guitar or violin, the vibrating tines of a tuning fork, or the vibrating diaphragm of a radio speaker.

Electromagnetic waves do not require a medium in order to transport their energy. Transverse waves have two parts—the crest and the trough. This means that frequency and wavelength are indirectly proportional to each other. First, there is a medium that carries the disturbance from one location to another.

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.

In fact, the more particles that can be made to vibrate, the louder or more amplified the sound. A sound wave is similar in nature to a slinky wave for a variety of reasons. Highest points of a wave Trough: A Love wave is a surface wave having horizontal waves that are shear or transverse to the direction of propagation.

The rarefaction is the farthest distance apart in the longitudinal wave and the compression is the closest distance together. To observe the transmission of waves in a slinky, rope and water surfaces Hypothesis: Typically, this medium is air, though it could be any material such as water or steel.

In turn, the sound box, being connected to the air inside of it, sets the air inside of the sound box into vibrational motion. Sound is a wave that is created by vibrating objects and propagated through a medium from one location to another. Lowest points of a wave Aim: With the room darkened, the strobe would allow us to view the position of the tines two times during their vibrational cycle.EXAMPLE OF A WELL WRITTEN LAB REPORT FOR.

James Grad, Dean Kieserman. Science 1/7/12 Frequency and Amplitude in Mechanical Waves 1.

Purpose: Research Question: If the frequency of a transverse wave is changed, does wavelength. Lab III - 1 LABORATORY III WAVES Mechanical waves allow us to transfer energy from one position to another without actually moving an object between those two positions.

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.

Feb 25,  · Best Answer: 1.A mechanical wave is a wave that requires a medium through which to transmit energy. Sound waves, waves in a Slinky, and pressure waves are all examples of this. Sound waves need air molecules in order to exist; the Slinky waves Status: Resolved.

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.
