How do flame colors vary for different elements? All electromagnetic waves travel at the speed of light (\(c\)), or \(3.0 \times 10^8 m/s\). Well, when an atom or ion absorbs energy, its electrons can make transitions from lower energy levels to higher energy levels. It was important to use a different wood splint for each test because the wood splint was contaminated by the prior element which would have effected the color of the element being tested. Differences in the wavelengths of visible light are manifested as different colors, shown in the color spectrum below (colors can be seen in the PDF document on-line). Using your data, identify the metal ion in your unknown solution. Clearly show any equations you have used.
