- The figure below depicts spectral reflectance measurements for three different materials: a green leaf from a healthy plant, a sheet of shiny blue paper, and the palm of a human hand. The measurements are labeled 1 (black line), 2 (red line), and 3 (blue line). Match the measurements to the most appropriate material typeThe Balmer series, or Balmer lines in atomic physics, is one of a set of six named series describing the spectral line emissions of the hydrogen atom. The Balmer series is due to transitions of electrons to the energy level with n=2. Using the ideas and treatment seen in class, find the three largest wavelengths corresponding to lines of the Balmer series. Express your results in nm.Use the worked example above to help you solve this problem. A sodium surface is illuminated with light of wavelength 0.329 µm. The work function for sodium is 2.46 eV.
