The resulting DNA-dye-complex best absorbs 497 nanometer blue light (λ max = 497 nm) and emits green light (λ ...
In astronomy, the color index is a simple numerical expression that determines the color of an object, which in the case of a star gives its temperature. The lower the color index, the more blue (or hotter) the object is. Conversely, the larger the color index, the more red (or cooler) the object is. This is a consequence of the logarithmic ...
