Time-varying systems, materials with properties that change over time, have opened new possibilities for the experimental ...

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the ...

Tyndall and Graham Bell are some of the scientists who laid the theoretical foundations for what would later become fibre ...

Understanding diffraction and dispersion is key to optical science, influencing technologies like spectroscopy, fiber optics, and advanced imaging systems.

I tried a series of amazing light experiments to explore reflections, refractions, and optical illusions, showing just how fun and surprising light can be. Donald Trump announces second military ...

Abstract: In this paper, a theoretical analysis of orbital angular momentum (OAM) wave propagation properties in terms of reflection and refraction is introduced by decomposing OAM waves into infinite ...

Researchers cracked the mystery of altermagnets, materials with no net magnetization yet strange light-reflecting powers, by creating a new optical measurement method. Their findings confirmed ...

Sponsor: OSU Extension & The Ohio State University College of Food, Agricultural, and Environmental Sciences Ever wondered how a kaleidoscope turns a few simple beads into endless, colorful patterns?

We study the analog of Snell's law for particles moving across the interface of two regions with two different potential energies, from two different points of view. First, a simple demonstration ...
