ID Code: N2-07
Purpose: Individual viewing of the Balmer series of hydrogen.
Description: The hydrogen spectral tube, used with its power supply as shown, is viewed individually by students holding small mounted pieces of holographic grating. The holographic grating produces a brighter but less dispersive spectrum than the standard replica grating, but is necessary because the hydrogen tube is not very bright. Please collect the holographic gratings; they are a bit more pricey than the hand-held replica gratings cut from a roll of material.
Availability: Available
