Product Summary
The wavelengths of the discrete lines of the atomic spectra of various gases are measured using a grating spectrophotometer.
The 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. First and second order lines are examined.
The wavelengths of the spectral lines are compared to the accepted values and, in the case of hydrogen, the electron orbit transitions corresponding to the lines are identified.
PASCO Advantage: The open construction of the spectrophotometer allows the entire spectrum to be seen, while the intensity vs. angle is graphed in real time.
Designed for use with any of the following
- 850 Universal Interface

- Any PASPORT interface with 2 ports
Concepts
- Hydrogen balmer series
- Helium spectrum
