PVC colour poster illustrating the electromagnetic spectrum on all wavelengths, from gamma rays to radio waves.
The visible spectrum of the sun and those of 8 chemical elements (Hydrogen, Helium, Neon, Sodium, Calcium, Strontium, Cadmium, Mercury) are particularly well represented.
This poster thus gives the absorption spectra of Chlorophyll and Potassium Permanganate.
Dimensions: 100 x 60 cm, with two eyelets
