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 ...

There is a lot more to light than what mere human eyes can detect, but a device in your pocket can help you see beyond your biological limits. Our eyes can only detect colors of light that we see as a ...

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 ...

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 ...

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 ...

We see our world in a variety of vibrant colors that often make us wonder how any of this is possible. But in truth, we can’t see that much light at all, at least if you factor in all the types of ...

As we all know, our most important source of visible light is the sun. Those of us who have stayed out in the sunlight on a bright summer's day a little bit too long also know that solar radiation ...

There are seven types of electromagnetic (EM) waves, which make up the electromagnetic spectrum. Electromagnetic waves are transverse waves, and travel at the speed of light. Different types of ...
