  2. Longitudinal waves are waves where the displacement of the medium is in the same direction as the direction of the travelling wave. The distance between the centres of two consecutive regions of compression or the rarefaction is defined by wavelength, λ.

  3. Mechanical longitudinal waves are also called compressional or compression waves, because they produce compression and rarefaction when travelling through a medium, and pressure waves, because they produce increases and decreases in pressure.

  4. Sound waves are mechanical waves that are defined as the motion of waves with compression (high-pressure region) and rarefaction (low-pressure region). What are Longitudinal Waves In a longitudinal wave, the displacement of the particle is parallel to the direction of the wave propagation .

  5. May 18, 2023 · Sound waves are made of vibrating molecules. Some molecules vibrate close together and other molecules vibrate farther apart, creating waves. Compression waves are also called longitudinal waves because the molecules vibrate parallel to the direction the wave is traveling.

  6. Longitudinal waves are sometimes called compression waves or compressional waves, and transverse waves are sometimes called shear waves.

  7. Longitudinal Waves. Longitudinal waves have the same direction of vibration as their direction of travel. This means that the movement of the medium is in the same direction as the motion of the wave. Some longitudinal waves are also called compressional waves or compression waves.

  8. Longitudinal Waves. Longitudinal waves have the same direction of vibration as their direction of travel. This means that the movement of the medium is in the same direction as the motion of the wave. Some longitudinal waves are also called compressional waves or compression waves.
