This innovative research demonstrates how lasers can be used to create and detect high-frequency surface acoustic waves using novel materials as a "wave guide." "The material is considered a soft ...

Acoustic oscillations in M67 stars reveal a surprising plateau in frequency patterns, providing a new tool to probe stellar ...

This is where two acoustic waves transfer energy to a surface wave by matching its frequency, which in turn causes the surface wave to get larger and more powerful (by increasing its amplitude).

For intense earthquakes, these surface waves can zip around the planet multiple ... the mightiest in the island's recorded history. Yet the frequency of these shakes has declined in recent months ...

A recent study has mathematically clarified how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. The researchers derived a new equation that characterizes ...
