Atomic Emission Spectra Lab Report. A diffraction grating splits a single beam of light into the many colors which it contains. Each element or compound has a distinct emission spectrum that can be used to help identify it. The discrete bright (dark) lines in the emission (absorption) spectrum can be explained by treating light as a photon that is emitted (absorbed) by an atom, as shown in Fig. That means show the numbers in the equation and the final answer with units. The spectroscope allowed light in through a slit, a method known as diffraction. The lines in the atomic spectrum of hydrogen are grouped into "series," where each member of a series involves a transition to the same lower energy level. Discussion/Conclusion: The results obtained from this lab are compatible with the theory behind electromagnetic radiation.

In a neutral atom there is the same number of electrons as protons. To estimate the wavelength of light produced‚ then calculate the frequency and energy of the light II. We observed and recorded the different wavelengths of the spectral lines emitted by each gas. Discussion/Conclusion: The results obtained from this lab are compatible with the theory behind electromagnetic radiation. In this experiment we will observe the wavelengths of various spectra and compute the frequencies of the waves using the equation: c = λf where c = speed of light = 2.99 x 108m/s λ = wavelength (meters) f = frequency (cycles per second = 1 / s = Hz) In 1900 Max Planck studied visible emissions from hot glowing solids. Every ion gives off a different light configuration based on the amount of energy they hold. 8. In this experiment a diffraction grating optical spectrometer is used to study the spectra. Safety: Standard safety procedures III. 3. Unlike traditional flame emission labs, where student see a bright burst of color, this procedure allows students to safely observe an emission spectra and use online tools to match the element.
