Longitudinal

Examples of Longitudinal in the following topics:

• Longitudinal Waves

  • An example of a longitudinal wave is a sound wave.
  • Some longitudinal waves are also called compressional waves or compression waves.
  • Like transverse waves, longitudinal waves do not displace mass.
  • Longitudinal waves can sometimes also be conceptualized as pressure waves.
  • A compressed Slinky is an example of a longitudinal wave.

• Waves

  • A wave can be transverse or longitudinal depending on the direction of its oscillation.
  • Longitudinal waves occur when the oscillations are parallel to the direction of propagation.
  • While mechanical waves can be both transverse and longitudinal, all electromagnetic waves are transverse.
  • Sound, for example, is a longitudinal wave.
  • In this chapter we will closely examine the difference between longitudinal and transverse waves along with some of the properties they possess.

• Water Waves

  • Water waves can be commonly observed in daily life, and comprise both transverse and longitudinal wave motion.
  • The uniqueness of water waves is found in the observation that they comprise both transverse and longitudinal wave motion.
  • In the case of monochromatic linear plane waves in deep water, particles near the surface move in circular paths, creating a combination of longitudinal (back and forth) and transverse (up and down) wave motions.
  • This is a result of the wave having both transverse and longitudinal properties.

• Characteristics of Sound

  • Sound is a longitudinal wave of pressure that travels through compressible medias, which can be solid, liquid, gaseous, or made of plasma.
  • Sound is a wave—a longitudinal wave of pressure that travels through compressible medias (i.e., solid, liquid, gaseous, or made of plasma).
  • Sound travels in longitudinal waves.

• Problems

  • Estimate the maximum longitudinal fluid velocity in the case of a sound wave in air at STP in the case of a disturbance which sets up pressure fluctuations of order 0.1\%.

• How about relativistic particles?

  • At first glance, the power from longitudinal motion seems much larger that the circular motion, but it is important to compare the power emitted for the same applied force ($d{\bf p}/dt$).
  • Radiated power as a function of angle and γ for longitudinal motion.

• Really Little Sound Waves

  • Therefore, the fluid is displaced in the direction of the propagation of the wave; it is a longitudinal wave.

• Standing Waves in Air Columns

  • In an air column, a standing wave can form as either a longitudinal or transverse wave.
  • A longitudinal wave, on the other hand, is parallel to the direction of propagation.

• Transverse Waves
