Transverse vs. Longitudinal Waves

Click For Summary
SUMMARY

The discussion clarifies the fundamental differences between transverse and longitudinal waves. In transverse waves, such as light waves and oscillations of a string, the displacement of the medium occurs perpendicular to the direction of wave travel. Conversely, in longitudinal waves, like sound waves, the displacement is parallel to the direction of wave travel. Additionally, water waves exhibit characteristics of both types, demonstrating the complexity of wave behavior.

PREREQUISITES
  • Understanding of wave mechanics
  • Familiarity with the concepts of displacement and wave propagation
  • Basic knowledge of light and sound waves
  • Ability to interpret wave diagrams and graphs
NEXT STEPS
  • Study the properties of light waves and their applications in optics
  • Explore sound wave behavior and its implications in acoustics
  • Investigate the dual nature of water waves and their classification
  • Learn about wave interference and superposition principles
USEFUL FOR

Students studying physics, educators teaching wave mechanics, and anyone interested in understanding the fundamental principles of wave behavior.

Homework Statement


Please explain the difference and try to give examples. I know that the displacement of the medium in a transverse wave is perpendicular to the direction of wave travel and in longitudinal is parallel to the direction of wave travel, but does this mean that transverse waves only travel from left to right?

The Attempt at a Solution



I've stated what I know above, and what I'm confused about. Please help.

I was going to write out the definitions and some examples, but I'll be lazy and just link you to wikipedia, because they seem to handle this question quite well.

http://en.wikipedia.org/wiki/Transverse_wave" : consists of 'particles' moving perpendicular to the direction the energy is moving in ("transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y-z plane"). Examples: light waves or moving a string up and down.

http://en.wikipedia.org/wiki/Longitudinal_wave" : the 'particles' are moving parallel to the direction of energy. Examples: sound

Water waves are both transverse and longitudinal.

This sight has some nice pictures too: http://www.kettering.edu/~drussell/Demos/waves/wavemotion.html
