Measuring bacterial growth at 600nm is a commonly used method because it corresponds well with bacterial cell density and is a quick and convenient way to monitor growth in real-time. The wavelength of 600nm falls within the range where bacterial cells absorb light due to their pigments like chlorophyll, carotenoids, and cytochromes, making it a suitable indicator of cell growth.
A wavelength of 600nm is commonly used for turbidimetry because it falls within the visible range of light and is less prone to interference from color or impurities in the sample. Additionally, 600nm is often near the absorbance peak for many turbid samples, providing optimal sensitivity for measuring turbidity.
Blue
600nm is 0.00006 cm
546nm light wavelength corresponds to a green color.
Pantone 357C corresponds to a mossy green color.
660nm light corresponds to the red-orange color in the visible spectrum.
A wavelength of 540 nm corresponds to the color green in the visible spectrum.
Red color will have the longest wavelength, which corresponds to the lowest energy in the visible light spectrum.
