Be the first to answer! Reader, C.J. Krypton chloride excimer laser Figure 7. In the late 1800s, it was known that when a gas is excited using an electric discharge and the light emitted is viewed through a diffraction grating; the spectrum observed consists not of a continuous band of light, but of individual lines with well-defined wavelengths. Emission spectra are produced when atoms of a dilute gas are `excited' -- in effect, heated -- by an electrical current, ultraviolet radiation, or … These authors give four or five place Kr II wavelengths of the 86 Kr isotope. Sulfur. Using the wavelengths recorded above, calculate the corresponding wavelengths, frequencies and photon energies for each compound tested. No color is dramatically favored over another, although the intensity is highest in the light blue region, around 460 nm. Aluminum. colors: nm: Line Emission Spectrum for Mercury. atomic emission spectrum: The pattern of lines formed when light passes through a prism to separate it into the different frequencies of light it contains. To cite either image, simply use the following text: This Java program reads a file containing a list of emission line wavelengths and their corresponding strengths then simulates the appearance of the spectrum in a good visual spectroscope. I am reasonably sure that all of these appear more or less as depicted. Asked by Wiki User. all wavelengths of emission spectra combine to form white light. colors: nm: Data Analysis.
