The discussion revolves around the purchase of polarized transducers capable of emitting sound at 25kHz. Participants explore the concept of polarized ultrasound and its feasibility, touching on the nature of sound waves and their classifications.
Participants express disagreement regarding the existence and nature of polarized ultrasound, with some asserting its impossibility while others provide counterarguments and examples of shear waves.
The discussion includes varying interpretations of sound wave behavior and the conditions under which different types of waves can exist, particularly in different media. The references to external articles suggest a reliance on specific applications and contexts that may not be universally applicable.
It's a trick question. There's no such thing as polarized ultrasound. Sound waves are longitudinal, not transverse.Serj said:
Ah, not so! While is virtually impossible to generate shear waves in gases, shear waves are possible in liquids and solids, or basically any elastic material.berkeman said:
