WebA wave of light has a wavelength, defined as the distance from one crest of the wave to the next, and written using the symbol . The 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. WebThe flame test is a crude analytic tool where a substance of unknown identity and/or characteristics is placed over a flame. Depending on the identity of the chemical, various things can happen when exposed to high heat. Most organic compounds will ignite or decompose in some manner or other.

WebFlame tests are used to identify the presence of a relatively small number of metal ions in a compound. Not all metal ions give flame colours. For Group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got.
