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 ...

Waves are ubiquitous in nature, allowing us to see, hear and observe. Because of such pervasiveness, the need to study how waves work proves to be an important one Nonlinear Waves in Bounded Media ...

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 ...

The researchers found that a slightly curved meniscus allows more wave energy to pass through the barrier. Conversely, if the meniscus curves more steeply, it reduces the energy transported by the ...

Can we reveal objects that are hidden in environments completely opaque to the human eye? With conventional imaging ...

The most dangerous waves on the planet are a combination of sheer, jaw-dropping awe and power. Only the world's most talented (or foolhardy) surfers would dare approach waves such as these.
