  2. Blue laser - Wikipedia

    en.wikipedia.org/wiki/Blue_laser

    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).

  5. Electromagnetic spectrum - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_spectrum

    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 ...

  6. Verdet constant - Wikipedia

    en.wikipedia.org/wiki/Verdet_constant

    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 ]

  7. 4-Nitrophenol - Wikipedia

    en.wikipedia.org/wiki/4-nitrophenol

    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 ]

  8. Photolithography - Wikipedia

    en.wikipedia.org/wiki/Photolithography

    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").
