Flame tests wavelengths scholarly
WebAnalysis: For each metal cation flame test performed, determine the wavelength corresponding to the observed flame color from the table below. Dominant Color Approximate Wavelength (in nm) Wavelength values here are given for the mid- Red 701 range of the color indicated. WebThe wavelengths of visible light are quite small: between 400 mm and 650 nm, where 1 nm = 10-9 m is a ``nanometer'' - one billionth of a meter. Red light has long wavelengths, while blue light has short wavelengths. A particle of light, known as a photon, has an energy E.
