The grid-pattern “square waves” that appear in viral social media posts each summer are ...

For decades, physicists searched in vain for evidence of gravitational waves, the stretches and squeezes in spacetime that were first predicted by Albert Einstein’s theory of general relativity a ...

There’s a connection between wave types that scientists once thought were fundamentally different.

"This is one more example of how the everyday ordinary world is full of wonders, if we only choose to see carefully." ...

The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

The waves you see at the shoreline are actually wind waves and are the sum of many components that were generated by the wind at a distant site. These components travel at different speeds, depending ...

We saw earlier that when sound waves come from correlated sources then their pressure and associated velocity components simply add. This meant that the pressure amplitude could vary between zero and ...
