Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

Recent physics studies have found that light can sometimes flow in unexpected ways, behaving like a so-called "superfluid." ...

The latest experiment also represents the first time the LZ team applied a technique called “salting,” in which false WIMP ...

Physicists tested the Greenberger–Horne–Zeilinger (GHZ) paradox, which is at the heart of quantum theory, to measure light ...

Spectroscopes split light into colors to create rainbows. They work by using a prism or diffraction grating to spread out light, like a rainbow. Scientists use spectroscopes to study stars and planets ...

Isaac Newton loved experiments. During an experiment with prisms, he discovered that a rainbow had several colors in it (red, orange, yellow, green, blue, indigo, and violet). Since these are the only ...

Light Refraction, it might sound like a big scary term, but today’s experiment is basically about rainbows! Who doesn’t love a rainbow experiment? These simple experiments are perfect for your ...

Bose himself never claimed that he had invented the radio. Twelve years after Marconi received the Nobel Prize for wireless telegraphy, Bose wrote, in a Bengali article published in 1921, ‘Invisible ...

Here’s how it works. Isaac Newton's ingenious experiment using prisms helped us understand light. (Image credit: Getty Images) ...
