The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye.

Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti sapphire laser.

Furthermore, the visual perception of many animals is influenced by a different visible spectrum than humans.

Hyperspectral imaging these systems acquire data over a range of wavelengths in the visible, short and long wave infrared (thermal) regions of the electromagnetic spectrum.

A simple thermal source is sunlight, the radiation emitted by the chromosphere of the Sun at around 6,000 Kelvin peaks in the visible region of the electromagnetic spectrum when plotted in wavelength units and roughly 44 of sunlight energy that reaches the ground is visible.

Primary properties of visible light are intensity, propagation direction, frequency or wavelength spectrum, and polarisation, while its speed in a vacuum, 299,792,458 meters per second, is one of the fundamental constants of nature.

A common thermal light source in history is the glowing solid particles in flames, but these also emit most of their radiation in the infrared, and only a fraction in the visible spectrum.

Photonics is the science of generating, controlling, and detecting photons (packets of light), particularly in the visible and near Infrared, but also extending to the Ultraviolet, Infrared and far IR portions of the electromagnetic spectrum.

The gas shows strong absorptions in the visible spectrum at 676.3 nm and 649.8 nm (red) the dissociation energy of the radium chlorine bond is estimated as 2.9 eV, and its length as 292 pm.

As the temperature increases, the peak shifts to shorter wavelengths, producing first a red glow, then a white one, and finally a blue white colour as the peak moves out of the visible part of the spectrum and into the ultraviolet.

The Schumann resonance is a set of spectrum peaks in the ELF portion of the Earth's electromagnetic field spectrum.

Cognitive radio technology, also known as smart radio allowing different radio technologies to share the same spectrum efficiently by adaptively finding unused spectrum and adapting the transmission scheme to the requirements of the technologies currently sharing the spectrum.

Could make some sort of landmark points along a spectrum of improbability, which might look like the electromagnetic spectrum we just looked at.

For example, in the US D, E, and F PCS spectrum blocks, the amount of spectrum available is 5 MHz in each direction.

Fortunately, there are visible and encouraging results.

However, this participation is not always visible.

The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight.

Little wonder that academics across the political spectrum have expressed considerable skepticism.
