Across the cosmos, many stars can be found in pairs, gracefully circling one another. Yet one of the most dramatic pairings ...

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 ...

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 ...

Kim explains how the new measurement was made, “The speed at which surface waves propagate depends on their frequency, which in turn depends on their depth." By measuring changes in velocity in ...

This is the frequency of the wave. Morrison and Cocconi considered how well the ... If a gold nugget is near the surface anywhere in the field, we’ll have a good chance of finding it. We could study ...

A recent study has mathematically clarified how the presence of crystals and gas bubbles in magma affects the propagation of ...

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).
