We explore double and single slit example problems involving light and sound waves. In this Closer Look segment on Diffraction and Interference, we explore double and single slit example problems ...

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same time. Matter no longer behaves like solid objects moving along clear paths.

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

Researchers have demonstrated a new technique to generate magnetic waves in antiferromagnets that propagate through the material at a speed much larger than the speed of sound. These so-called spin ...
