Visible spectrum

Color skepticism is the belief that nothing truly possesses colors, since they are merely appearances to the perceiver. Although this is a sole belief on its own, there are many ways in which people have attempted to prove its validity. Some points of view include considering the scientific process behind the perception of color, while others, through a scientific lens, concentrate on what color really is, including its potential properties. However, I believe that the theory that is the most…

The purpose of the Determining Food Dye Content Lab was to identify the food dye coloring in green apple Gatorade, and determine the dye’s concentration to ultimately recreate a solution containing the same concentration of dyes as the original. To determine the concentration of the dyes present in the green apple Gatorade, a spectrometer was used to measure the wavelengths and absorbance values for the given dyes. A sample of the green apple Gatorade was tested in the spectrometer to measure…

Process information: Interpret and discriminate Mrs. Checketts’s paper thin skin is observed. Normal skin varies in thickness from 0.2 to 1.5 mm depending on individual’s age (Estes 2013). As the skin ages, the thickness of the dermis decreases and becomes translucent due to loss of the rete pegs (McCance & Huether 2010), Mrs.Checkett’s thin skin is therefore a normal biological process and an anticipated age related change. A small pressure injury is noticed on Mrs. Checketts’s coccyx.…

Visible Light Communication – Tomorrow’s Technology YASHODHA J K NITHYASHREE N Weir EnSci, Bengaluru Weir EnSci, Bengaluru yashodhajk@gmail.com Nithyashree0292@gmail.com Abstract-The Visible Light Communication (VLC) is an emerging technology, which provides distinct facilities such as fast data communication, secure data communication, high data rate wireless communication, etc. Instead of radio frequency, VLC uses light, to transfer data. The visible light spectrum is unlicensed…

the dilute concentrations are in Results section. The concentration for each tube were as follows: 0.015 mg/ml for tube 1, 0.0075 mg/ml for tube 2, 0.00375 mg/ml for tube 3, 0.001875 mg/ml for tube 4, and 0.000935 mg/ml for tube 5. The absorption spectrum was performed for cuvette 1 to determine the maximum absorbance wavelength Figure 1. Cuvette #6, with 5ml of distilled water, acted as a blank to recalibrate the spectrophotometer to 0.000 absorbance between changing wavelengths.…

man named James Clerk Maxwell found that one specific group of electromagnetic waves was the cause of visible light, or the cause of color. Maxwell also identified…

identified or characterized by the use of electromagnetic radiation. Electromagnetic radiation not only includes light (or photons), but thermal energy as well. While the electromagnetic spectrum consists of wavelengths between gamma radiation and the Far IR, most spectrophotometric methods rely on the UV and visible region. In order to use spectrophotometric methods, the sample being analyzed must be able to absorb the energy (photon) used to excite the sample. UV-Vis and other optical…

When a lens produces an image, the size of it corresponds to the focal length of the lens. The smaller the focal length, the smaller the image and the longer the focal length the bigger the image. How bright an image may be solely depends on the amount of light collected by the objective lens. How much light can be collected corresponds to the area of the objective lens. So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you…

The visible pulse (gating pulse) enters the microscope, and together with the ultrafast electron pulses illuminate the nanostructure specimen (gold nanoparticle). The visible laser pulse kept at low power (~1.8 mJ/cm2) to avoid saturation. At the spatiotemporal overlapping, the coupling between the visible and electron pulses takes place. The signature of this coupling can be revealed by measuring the electron energy spectrum using the electron energy spectrometer attached to the microscope. The…

Or, well, not just “gay”, but on the LGBTQIA+ spectrum. That’s lesbian, gay, bisexual, transgender, queer, intersex, asexual and a whole lot more. Obviously…
