    The observed colour was orange, which fit the emission spectrum. Few specks of blue were observed, this might be due to the Bunsen burner not being completely cleaned or the sodium not being completely pure. The observed colours match those of the spectrum, and can be accepted as true. The observed colour for lithium was a dark red colour. Lithium’s emission spectrum consists of purple, blue, cyan and red. Few darker specks of blue were observed, possibly from the same substance that made the specks, when sodium was burned. The observed dark red colour fits the emission spectrum of lithium, and can therefore be accepted as true. Potassium burned a bright pink/purple colour, which fits the emission spectrum of potassium. The spectrum contains…

    When flame test research is performed on an element, it is easy to see the color changes just by physically observing it. Often, many elements can have similar emission spectra’s, which is why Kirchhoff invented the Spectrometer. This is a specialized device that uses a prism and two mirrors that allow the light to be conducted into its unique emission spectra. From elements such as lithium to others like selenium, every single element has its own unique color or elemental fingerprint; this is…

    would lead to different solutions. I believe that the NDP would want to have as many immigrants to move,live and work in Canada. Based on my knowledge of the political spectrum, the NDP wants to bring in immigrants quickly and would want changes to occur immediately. They would try to lower the barrier for immigrants coming to Canada to better help the people in need. The Green party would want to allow as many immigrants to move to Canada and provide job opportunities. They also want to think…

    takes place. The signature of this coupling can be revealed by measuring the electron energy spectrum using the electron energy spectrometer attached to the microscope. The measured electron spectrum is shown in blue line curve in Fig. 2A. The white reddish part of the spectrum represents the ZLP while the shaded blue part shows the gated electron spectrum. The temporal profile of the “original” ultrafast electron pulse…

    of objects, which is represented on the spectrum of color they radiate. An interaction of electromagnetic radiation with matter. Spectroscopy involves the process of absorption, emission, or scattering of electromagnetic radiation by either ions, atoms, or molecules. The process of absorption involves when light is absorbed by electrons that jump to higher energy levels. On the other hand, emission spectra are established when the electrons from high energy levels give off light to jump…
