We’re all familiar with sunshine, but did you know there are many different kinds, including infrared, ultraviolet, and many shades of visible sunlight?
The emission spectra for FAM and VIC peak at 517nm (in the blue region of the visible spectrum) and 551nm (in the green region) respectively (Figure 1), making these wavelengths easily distinguishable by any Applied Biosystems real time PCR instrument. Top Three...
"Spectrum" refers to a range of different things, often colors or wavelengths, while "spectra" is its plural form, indicating multiple ranges or sets.
In this International Year of Light, it is particularly appropriate to review the historical concept of what is light and the controversies surrounding the extent of the visible spectrum. Today we recognize that light possesses both a wave and particle nature. It is also clear that the limits of...
Colour can be described in terms of hue (dominant wavelength of the visible spectrum), saturation (the amount of white light mixed in with a hue) and brightness (intensity of light). Any desired hue of light can be produced when various amounts of the three primary colours of light (red...
Don McCullough/Flickr/CC-BY-2.0 The color spectrum is the entire range of light wavelengths visible to the human eye.These range from approximately 400 nanometers per wavelength, at the violet end of the spectrum, to 700 nanometers per wavelength, at the red end of the spectrum. ...
Light waves come in many sizes, or wavelengths. The light we can see is only a very small part of the spectrum of light waves that exist. Ultraviolet light is part of the electromagnetic spectrum beyond visible light. Humans cannot see ultraviolet light, but some insects, such as bees, ...
Wavelengths are typically measured in the following units: Kilometers (km). Meters. Millimeters. Micrometers (μm). Nanometers. Picometers (pm). Femtometers (fm). The latter unit is used to measure shorter wavelengths on the electromagnetic spectrum, such as UV radiation, X-rays and gamma ...
Below we’ll discuss how blue light differs from other light wavelengths, the effects it has on your body (both good and bad), and simple ways you can control your exposure. What Is Blue Light? Visible blue light is the portion of the visible light spectrum that has the shortest wavelengt...
Light spectrum only has a few wavelengths (not all) or lines. Atoms tend to absorb some wavelengths when electromagnetic radiation is passed through them which display only a few narrow absorption lines when recorded. The major difference between these two is that continuous spectra has all the ...
