WINDOWS During the Apollo (manned lunar exploration) space
... For parallel rays of visible light passing through a window, one medium probably will be air (n1 = 1.0). The other probably will be some other glass (n2 ~ 1.5). Using Equation 3, you can calculate a reflection of ~ 4%. This calculation is for one side of the window. When the rays emerge from the oth ...

Ultraviolet–visible spectroscopy
Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
