Students understand atomic line spectra in a whole new light.

• Teacher's manual included

• Purpose for students: to understand atomic spectra and spectral line analysis

The spectrum tube power supply and diffraction grating are positioned so that the spectral lines may be observed from a known distance. With the FUN stand on its side, the colored rods are moved so that they align with the spectral lines students observe through the diffraction grating. By applying the double slit diffraction equation, students can also calculate the wavelength of each spectral line based on the distance of the colored rods from the central axis with metric tape and diffraction grating.

Students can also calculate the wavelength of each colored rod based on its distance from the central axis with metric tape and diffraction grating.

At least one FUN stand is required, but available separately. Also required is a spectrum tube power supply and gas emission tubes.

This kit includes colored rods, a support stand, instructions, metric tape, and diffraction grating.
