Recording of Absorption Spectra, Leybold Products

Leybold Chemistry Experiments.

• Observe and understand light spectra
• Recognize connection between absorption, reflection and transmission
• Appreciate color as light of characteristic wavelengths
• Identify the interaction of light with colored liquids

In experiment C3.3.1.2, the solution of a dye is exposed to the light from a lamp. For the absorption spectrum, the light passing through the colored solution is recorded with a spectrometer. The absorption spectrum is compared with the continuous spectrum of the light from the lamp.
