The speed of light in a vacuum, clocking in at a showy 299,792,458 meters per second (98,3571,056 feet per second), plays a pretty darn important role in the laws of physics as we understand them ...

This film demonstrates the measurement of the speed of light in both air and water using experimental setups. The first experiment involves measuring the time it takes for light to travel a known ...

An international team of scientists led by researchers at the Peking University in China has designed a revolutionary ‘all-optical’ chip that uses light to synchronize the speed of processors ...

Taara is a silicon photonic chip, which is a technical way of saying it transmits data through the air using beams of light. The original version of Taara worked, but it had limitations — namely ...

Friday's boating tragedy on the St. Johns River is a reminder of the dangers on the water much like the road. Here are some ...

Warning letters to car owners are in the mail, as the first stage of Hawaii’s photo speed enforcement program gets underway.

The Alphabet “moonshot” project is launching a new chip to deliver high-speed internet with light instead of radio waves.

Electromagnetic radiation is the general term for the more familiar light and radio waves, but also includes gamma rays, x rays, ultraviolet rays, and infrared. All of these forms of electromagnetic ...
