Hydrogen Balmer Series
PHY370
Lab PDFStudents treat the Sodium emission doublet viewed through a grating spectroscope as known wavelengths and measure diffraction angles as precisely as possible in order to solve the diffraction equation for the grating spacing. Hydrogen spectral angles are then carefully measured and used along with the grating spacing to calculate the hydrogen spectral wavelengths.
