argon-ion lasers at 458 and 488 nm [5] Lasers emitting wavelengths below 445 nm appear violet, but are nonetheless also called blue lasers. Violet light's 405 nm short wavelength, on the visible spectrum, causes fluorescence in some chemicals, like radiation in the ultraviolet ("black light") spectrum (wavelengths less than 400 nm).
Thickness of the Ge 40 Se 60 /Si film on the silicon substrate as 34.5 nm, Thickness of the Ge 40 Se 60 /Si film on the oxidized silicon substrate as 33.6 nm, Thickness of SiO 2 (with n and k spectra of SiO 2 held fixed), and; n and k spectra, in 190–1000 nm range, of Ge 40 Se 60 /Si.

Electromagnetic radiation with a wavelength between 380 nm and 760 nm (400–790 terahertz) is detected by the human eye and perceived as visible light. Other wavelengths, especially near infrared (longer than 760 nm) and ultraviolet (shorter than 380 nm) are also sometimes referred to as light, especially when the visibility to humans is not ...
The Faraday effect is chromatic (i.e. it depends on wavelength), and therefore the Verdet constant is quite a strong function of wavelength. [ 5 ] [ 6 ] At 632.8 nm , the Verdet constant for TGG is reported to be −134 rad /( T ·m) , whereas at 1064 nm it falls to −40 rad/(T·m) . [ 7 ]
The yellow color of the 4-nitrophenolate form (or 4-nitrophenoxide) is due to a maximum of absorbance at 405 nm (ε = 18.3 to 18.4 mM −1 cm −1 in strong alkali). [4] In contrast, 4-nitrophenol has a weak absorbance at 405 nm (ε = 0.2 mM −1 cm −1 ). [ 4 ]
These lamps produce light across a broad spectrum with several strong peaks in the ultraviolet range. This spectrum is filtered to select a single spectral line. From the early 1960s through the mid-1980s, Hg lamps had been used in lithography for their spectral lines at 436 nm ("g-line"), 405 nm ("h-line") and 365 nm ("i-line").
The cited Andersland Charts include corresponding water content percentages for easy measurements. The TPRC Data Book has been quoting de Vries with values of 0.0251 and 0.0109 W⋅cm −3 ⋅Kelvin −1 for the thermal conductivities of organic and dry mineral soils respectively but the original article is free at the website of their cited ...
