Imagine, right now, as you read these words, you're immersed in an unseen ocean of energy. Waves are zipping through your ...

The electromagnetic spectrum is the range of all possible electromagnetic radiation. Above infrared in frequency comes visible light. This is the range in which the sun and stars similar to it emit ...

As great as cameras that operate in the visual light spectrum are, they omit a lot of the information that can be gleaned from other wavelengths. There is also the minor issue that visibility is often ...

Due to how light travels, we can only see the most eye-popping details of space—like nebulas, supernovas, and black holes—with specialized telescopes. Electromagnetic Spectrum: the visible range ...

Terahertz radiation, or T-rays, has barely been exploited compared to most of the rest of the electromagnetic spectrum. Yet T-rays potentially have applications in next-generation wireless ...

Radio is cool and exciting because it allows us to send voice and broadband data through the air. Advances in radio technology have resulted in more throughput, greater reliability and better range.

The Pentagon long has made a big effort to showcase its budding cyberwarfare capabilities. But the military has been less forthcoming about a key, more tangible component of cyber -- electronic ...

Electromagnetic wave is a wave consisting of electric and magnetic fields oscillating and traveling on the same direction. Light is an example of an electromagnetic wave and light in general is part ...

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 ...
