A widely-held understanding of electromagnetic radiation has been challenged in newly published research. The study found that the normal direct correspondence between the bandwidths of the current ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of ...

You will learn about semiconductor light-emitting diodes (LEDs) and lasers, and the important rules for their analysis, planning, design, and implementation. You will also apply your knowledge through ...

New experiments are pushing our understanding of light and optics to the limit and are also opening up new areas of physics and novel applications. (Picture credit: Photodisc) Optics has always been ...
