Examples. Longitudinal waves include sound waves (vibrations in pressure, particle of displacement, and particle velocity propagated in an elastic medium) and seismic P-waves (created by earthquakes and explosions).
In a dream about the ocean or sea, the calmness or turbulence of the water and ocean waves can be an indication of your emotional state. For instance, a tidal wave or tsunami might suggest being overwhelmed by your emotions or you may be afraid of being swept away by the stresses in life.
Tsunami / Tidal Wave Dream Interpretation. ... In general, a rising tsunami or a tidal wave within a dream represents repressed feelings and emotions. Seeing or observing a tidal wave without being in the situation means that you are experiencing unhappiness and emotional instability in a waking life.
The Meaning of a Tidal Wave in a Dream or Tsunami Dream. ... This is usually a helpful thing to do when our emotions get so strong that they well up into a massive wave! Tidal waves often appear in our dreams when are under a lot of pressure or when significant change is occurring.
In general, a rising tsunami or a tidal wave within a dream represents repressed feelings and emotions. Seeing or observing a tidal wave without being in the situation means that you are experiencing unhappiness and emotional instability in a waking life.
Transcript of The parts of Compressional and Transverse waves. points. Compressional Waves Don't have crests or troughs, but they do have compressions and rarefactions. In a compressional wave: It's measured from rarefaction to rarefaction or compression to compression It's measured in hertz ( Hz).
Definition of compressional wave. : a longitudinal wave (such as a sound wave) propagated by the elastic compression of the medium — called also compression wave.
However instead of crests and troughs, longitudinal waves have compressions and rarefactions. Compression. A compression is a region in a longitudinal wave where the particles are closest together. Rarefaction. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.
Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves.
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. ... Some of the most common examples of mechanical waves are water waves, sound waves, and seismic waves. There are three types of mechanical waves: transverse waves, longitudinal waves, and surface waves.
Waves are made up of compressions and rarefactions. Compression happens when molecules are forced, or pressed, together. Rarefaction is just the opposite, it occurs when molecules are given extra space and allowed to expand. Remember that sound is a type of kinetic energy.
Consider using these sound-absorbing tools: Thick Carpeting & Padding: Generally, the rougher the surface of carpeting (think shag), the more sound waves it absorbs. Sound- Absorbing Foam: ... Soundproof Blankets: ... Heavy Drapes: ... Overstuffed Pieces of Furniture: ... Filled Bookcases Lining the Walls:
Soundproof Cow's Sound Absorption Products: Acoustic fiberglass. Acoustic foam. Echo Absorber™ Acoustic Cotton. Acoustic Partitions. Hanging Baffles. Other Foams. Quiet Board™ Water Resistant Panels.
Compression is the process of lessening the dynamic range between the loudest and quietest parts of an audio signal. This is done by boosting the quieter signals and attenuating the louder signals. The controls you are given to set up a compressor are usually: ... as compression often attenuates the signal significantly.
Compress your files before sending Navigate to the folder that contains the file you want to send. Select a file. ... Right-click the selection, select Send To > Compressed (zipped) Folder. This creates a new zip file that contains the file or files you selected in step 2.
Examples of these waves are: vibrations in strings, ripples on water surface and electromagnetic waves. In a transverse wave, the particles of the medium oscillate in a direction perpendicular to the direction of propagation as shown in the figure.

A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist.

There are three categories: Longitudinal wave *s - Movement of the particles are parallel to the motion of the energy. ... Transverse wave *s - movement of the particles are at right angles (perpendicular) to the motion of the energy. ... Surface wave *s - particles travel in a circular motion.

Transcript of Classification of Waves. The speed of the wave depends on the medium through which it travels. The particles of the medium vibrate perpendicularly to the direction of wave energy. The displacement of the particles of the medium are parallel to the direction of wave propagation.
File compression is used to reduce the file size of one or more files. When a file or a group of files is compressed, the resulting "archive" often takes up 50% to 90% less disk space than the original file(s). Common types of file compression include Zip, Gzip, RAR, Stuff It, and 7 z compression.
