Flame test wavelengths
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. WebA fire place can give off photons with a wavelength of 1.5 x 10-3 millimeters and the X-rays used in a dentist’s office have a wavelength of 2.1 x 10-11 meters. Ultraviolet rays, the ones that give you sunburn or fade the colors of clothes have a …
