What is a longitudinal wave?
Long -term wave is oscillation or vibration that travels in the medium in parallel with the direction of movement. When one vibration particle is disturbed, it transmits interference to the next particle and transports the energy of the wave. Once energy is transported, the media particles are moved by left and right movement. For example, if the longitudinal wave travels to the east through the medium, the interference will vibrate in parallel in the alternating direction from left to right instead of moving the transverse wave up and down. The main difference between them is that electromagnetic waves can transmit energy through vacuum, while non -electromagnetic waves cannot. Non -lecturers include pressure and sound waves. Plasma waves are considered an electromagnetic longitudinal wave.
P-vlny or pressure waves are a type of compressive or elastic wave that can travel through various media, such as gases, solids and liquids. During the seismic event, pressure waves are formed due to alternating compression and decompression. For example, oscillation produced by the earthquakeIt causes vibrations that travel on the ground and water. Of all types of seismic waves, pressure waves are considered the fastest, allowing them to travel long distances. The pressure waves are recorded by a tool called seismometer, which measures ground movements.
earthquake can also produce sound waves. Like pressure waves, the sound waves of a compression nature are, which means that the waves are expanding and compressing the mass while moving. Sound waves, like P-Vlny, require medium energy transport from one area to another. The speed at which the sound travels depends on the medium it passes. Generally, Ond's Svlny travel faster in the solid media versus unheated media, such as air.
The use of a tuning fork is a good example of how the sound is produced and transmitted by the air medium. Fork movements produce vibrations that disrupt air particles and create a series of compression and decompression andKCE. As a result, these actions create a pure musical note.
Unlike pressure and sound waves, plasma waves cannot be made directly from the earthquake. Instead, the waves in the plasma must be generated from an electric or magnetic source. Laser is an example of a device that produces waves in plasma when it interacts with ionizing gases. This type of longitudinal wave may exist in an ionized or charged state. The electromagnetic wave may also take the form of a transverse wave, while the pressure wave will always be a longitudinal wave.
