Showing upon excitation with light of 370 nm at a wavelength of lambda max a maximum emission intensity i0 and at lambda max+30 nm an emission intensity i, such that i is less than or equal to 0.20 i0doi:US6730243 B2A CsBr:Eu phosphor showing a narrow emission spectrum upon UV-...
Changes in the acoustic backscatter of pelagic organisms in response to artificial light from the ship were different at each of the three stations (Fig.2). These responses were tested by turning on the ship’s lights after a period of total darkness. At stations A and C, the total acousti...
Japan) was used to determine the size and shape of the nanostructures. UV–Visible, GBC Cintra 3030 at the range 190–900 nm spectrophotometer was used to measure the optical absorbance of these samples. Using the BELSORP
In this study, we decided to compare the clinical effect and tissue changes caused by 660 nm and 780 nm exposure in an experimental model of OM induced by ionizing radiation. For this, the same laser protocols were used to infer the direct role of each wavelength on the different phases of...
Plants respond to different aspects of light, including the intensity, duration, wavelength, and direction [7,8]. In general, their response differs according to other environmental cues, genotype, season, cultivation practices, and many others [9]. Light is the only energy source for photosynthes...
the wavelength. Waves with longer wavelengths have lower frequencies. Mathematically, we can express this asc=λfc=λfwhere the Greek letter for “l”—lambda, λ—is used to denote wavelength andcis the scientific symbol for the speed of light. Solving for the wavelength, this is expressed ...
4a and 4b which illustrate respectively a sinusoidal phase grating of half wavelength depth and an idealized curve of zero-order transmission plotted as a function of the ratio of the grating depth to the wavelength of the light; FIG. 5 comprises FIGS. 5a and 5b which illustrate the effect ...
The frequency of violet light is about twice that of red light. How does the energy of a violet photon compare with the energy of a red photon? Red light has a longer wavelength than violet light. Which has greater frequency? The ...
A wavelength splitter is optically coupled to the other termination of the multi-fiber cable for producing light beams of different wavelengths, each illuminating the optical termination of one or more lambda-dedicated tap fibers or multi-fiber cables. From the wavelength splitter depart a number of...
CONSTITUTION:The laser light emitted by the light source 1 is diffused spectrally in the prism 10 and projected from a surface 10b, and light with specific wavelength lambda0 is incident on an optical fiber 4. The Stokes' light in the back Raman scattered light from the optical fiber 4 ...
