470nm

470nm refers to a specific wavelength of light, measuring 470 nanometers. This falls within the visible spectrum, and is perceived by humans as blue. The color blue is associated with various phenomena and applications. In nature, blue light is emitted by many stars, contributing to their spectral classification. On Earth, the sky appears blue due to Rayleigh scattering, where shorter wavelengths of light, like blue and violet, are scattered more effectively by atmospheric particles. Artificial sources of 470nm light include certain types of LEDs, which are commonly used in lighting, displays, and indicator lights. This wavelength is also utilized in phototherapy, particularly for treating neonatal jaundice. The blue light helps break down bilirubin in the blood, a common condition in newborns. Furthermore, 470nm light has applications in scientific research, such as in spectroscopy and fluorescence microscopy. Its interaction with different materials and biological samples can reveal valuable information.
