Researchers at the National Physical Laboratory (NPL) are developing systems of materials whose properties can be varied to change how they reflect and absorb electromagnetic radiation. These ...

Scientists have observed something called "time reflections" in electromagnetic waves, according to a paper published in the journal Nature Physics. It's an exciting discovery that has been theorized ...

Prediction of the upward-to-downward reflection ratio of glass bead retro-reflective material applied to the outer walls of buildings Jihui Yuan (Assistant Professor, Department of Architecture and ...

The American Society for Radiation Oncology (ASTRO) announced today that it rebranded its research foundation, formerly the ...

FOLLOWING the investigations of Laue, Friedrich, and Knipping, we were led to study the transmission of a narrow pencil of X-rays through rock salt, a crystal of simple cubic form. The results are of ...

Time reflections, or spatial reflections, occur when "electromagnetic radiation in the form of light or sound waves hit a mirror or wall, respectively," resulting in a reflection, like a mirror image ...
