Hydrogen Emission and Absorption Spectra

Students use a spectrometer, fiber optics cable, a hydrogen gas spectrum lamp, and the sun to compare emission and absorption lines, study atomic structure, associate light energy and wavelength with electron transitions, and calculate the Rydberg constant.

Featured Equipment

Spectral Tube (Hydrogen)

This Hydrogen Spectral Tube is 26-cm-long and capillary-thin over the middle 10-cm to provide sharp, bright spectra.

Spectral Tube Power Supply and Mount

Easy to use and inexpensive with a variety of safety features that make it suitable for beginning labs.

UV-Vis Fiber Optic Kit

Fiber Optic Kit, including a quartz core cable and an attached reflective cuvette to reflect the light perpendicularly into the detector. Designed specifically for use with the PASCO UV-Vis Spectrometer (SE-3607).

UV-Vis Spectrometer

Highly accurate spectrometer with broad range, ultraviolet through visible light illumination for detailed spectroscopic techniques in chemical structure and concentration determination.

Fiber Optic Cable

Facilitates emissions spectroscopy experiments with the PASCO Wireless Spectrometer. Simply insert the Fiber Optic Cable into the cuvette holder and point the end of the cable at the light source.

Wireless Spectrometer (Vis)

Measures intensity, absorbance, and transmittance across the visible spectrum. Includes fluorescent excitation at 405nm and 500nm.

Support

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
