WebThe atomic spectra of hydrogen, helium, and mercury are scanned by hand using a grating spectrophotometer, which measures relative light intensity as a function of angle. From the resulting graph, the wavelengths of the spectral lines are determined by measuring the angle from the central maximum to each line. WebExpert Answer 1The helium discharge lamp produces more distinct spectral lines than the hydrogen lamp because helium has more electrons and protons than hydrogen, w … View the full answer Transcribed image text: 1. Why does the helium discharge lamp produce more distinct spectral lines than the hydrogen lamp? (Clearly explain.) Web1 sep. 2024 · The spectral lines are grouped into series according to n1 values. Lines are named sequentially starting from the longest wavelength/lowest frequency of the series, using Greek letters within each series. For example, the ( n1 = 1 / n2 = 2) line is called "Lyman-alpha" (Ly-α), while the ( n1 = 3 / n2 = 7) line is called "Paschen-delta" (Pa-δ). flying high again solo
