Transverse Waves: Why They Can't Travel Through Liquids

Click For Summary

Discussion Overview

The discussion centers on the question of why transverse waves cannot travel through liquids, exploring the nature of wave propagation in different mediums, particularly focusing on fluids and their properties.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant states that fluids cannot support shear, which leads to the conclusion that only longitudinal pressure waves can propagate through them.
  • Another participant mentions that transverse surface waves can exist at shorelines, suggesting a distinction between surface and bulk wave behavior in fluids.
  • A question is raised about the relationship between transverse waves and shear, indicating a desire for deeper understanding of the underlying mechanics.
  • A reference to a geophysical explanation is provided, implying that external resources may offer additional insights into the topic.

Areas of Agreement / Disagreement

Participants present differing views on the nature of wave propagation in fluids, with some asserting that transverse waves cannot exist in bulk liquids while others point to specific conditions under which surface waves can occur. The discussion remains unresolved regarding the implications of these observations.

Contextual Notes

There are limitations in the discussion regarding the definitions of wave types and the conditions under which different wave phenomena occur in fluids. The relationship between shear and wave propagation is not fully explored.

Why transverse waves cannot travel through liquids ?
 
Physics news on Phys.org
A fluid (liquid or gas) is a substance that cannot support shear. So only pressure waves, which are longitudinal can traverse through a fluid.

However transverse surface waves can exist as you can witness at any shoreline.
 
What is the relation between transverse waves and shear?
