WebSep 22, 2024 · When heated in a flame, the element Indium emits electromagnetic radiation with a distinctive indigo blue color (the name indium is derived from the word indigo). The emitted photons that give rise to this color have energies of 4.405 × 10 − 19 J. Calculate the wavelength of this radiation in nanometers. Exercise WebThe next job is to do your flame tests. Dip the flame test loop into one of the known test solutions, then hold the metal loop in the edge of the Bunsen burner flame. Make a note of the colour of the flame on your Flame Test Chart (a simple version is shown below). Clean the flame test wire, then test another known test solution.
