As waves travel, they set up patterns of disturbance. The amplitude of a wave is its maximum disturbance from rest (its undisturbed position). Key fact It is important to note that the amplitude ...

Researchers have reviewed metamaterials to emulate Schrödinger dynamics, bridging classical wave physics and quantum ...

Waves in water are transverse. This means that the vibrations causing the waves are perpendicular to the direction of energy transfer. As this little boat demonstrates, you can see that the waves ...

Li and his team report that single-wavelength focal spots can be achieved ... lasers in the application of strong-field laser physics, such as vacuum quantum electrodynamics," says Li.
