Electrical engineers have discovered that changing the physical shape of a class of materials commonly used in electronics can extend their use into the visible and ultraviolet parts of the ...

UV radiation is a part of something that you may faintly remember from your K-12 or collegiate years called the electromagnetic spectrum (below). Electromagnetic energy propagates in wave form and ...

PHOENIX — Ultraviolet light is a type of electromagnetic radiation. It's responsible for the glow in a black light poster, or the bronze on your skin from a summer tan. Overexposure to UV radiation ...

Scientists have developed the first refractive lens that focuses extreme ultraviolet beams. Instead of using a glass lens, which is non-transparent in the extreme-ultraviolet region, the researchers ...

In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves ...

One of the landmark discoveries of 19 th century physics was the realisation that electricity, magnetism and light are all connected. Experiments had already shown that the movement of electrical ...
