University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

A plasma experiment succeeded in twisting light-like waves, and revealed a new, previously unknown rule of extreme physics.

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

Light is more than what we see. The Sun sends out a number of waves of light in different wavelengths. Find out about wavelengths and the electromagnetic spectrum. Science Trek is available to stream ...

And an international team of physicists appears to have found just such a loophole: the only thing that goes faster than light, it turns out, is darkness. More specifically, individual dark spots ...

We are surrounded by waves. tiny vibrational waves transport sound to our ears. Light waves stimulate the retinas of our eyes. Electromagnetic waves bring radio, television and endless streaming ...

Your phone warms up after a 20-minute FaceTime call. Your laptop hums loudly while editing a large video file. Heat is a ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By transferring minute amounts of energy between light and gravity, the interaction ...
