Periodic signal analysis enhances optics and photonics experiments using lock-in amplifiers and boxcar techniques.

As high school students see in experiments with water waves, and we observe and use with light waves in many optical devices, interference is a fundamental property associated with wave-like behavior.

Complementarity A new twist on the double-slit experiment. (Courtesy: Shutterstock/Andrey VP) One of the most counterintuitive concepts in physics – the idea that quantum objects are complementary, ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

Researchers from Australia’s University of Queensland have made a microscopic “ocean” on a silicon chip to miniaturise the study of wave dynamics. The device, made at UQ’s School of Mathematics and ...
