what do you mean by longitudinal wave
Answers
Answer:
longitudinal wave is a wave in which the particle movement is parallel to the direction of the wave propagation. This means that the particles move left and right which in turn makes the other particles start to oscillate. ... Longitudinal waves are also called pressure waves, and sound waves are the most common kinds.

Answer:
Longitudinal waves are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of propagation of the wave. Mechanical longitudinal waves are also called compressional or compression waves, because they produce compression and rarefaction when traveling through a medium, and pressure waves, because they produce increases and decreases in pressure.
The other main type of wave is the transverse wave, in which the displacements of the medium are at right angles to the direction of propagation. Some transverse waves are mechanical, meaning that the wave needs an elastic medium to travel through. Transverse mechanical waves are also called "shear waves".
By acronym, "longitudinal waves" and "transverse waves" were occasionally abbreviated by some authors as "L-waves" and "T-waves" respectively for their own convenience.[1] While these two acronyms have specific meanings in seismology (L-wave for Love wave[2] or long wave[3]) and electrocardiography (see T wave), some authors chose to use "l-waves" (lowercase 'L') and "t-waves" instead, although they are not commonly found in physics writings except for some popular science books
