Reflectivity vs wavelength
WebFeb 12, 2024 · Depending on the range of wavelength of light source, it can be classified into two different types: UV-visible spectrophotometer: uses light over the ultraviolet range (185 - 400 nm) and visible range (400 - 700 nm) of electromagnetic radiation spectrum. WebOptical properties. Water is transparent to the wavelengths of electromagnetic radiation that fall within the visible spectrum and is opaque to wavelengths above and below this band. However, once in the water, visible light is subject to both refraction and attenuation. Light rays that enter the water at any angle other than a right angle are ...
