Light Perception - Results
Measuring attenuation of wavelengths in a tunnel at different distances from the illuminated
tunnel opening, it became clear that the spectral range between 400 and 500 nm (blue) was
already not, or not well, propagated anymore at a distance of 5 cm from the light source.
Wavelengths from 500 nm to 700 nm (green and red) were still detectably propagated until a
distance of 60 cm. Even at 65 cm distance, there were still some measurable photons in the
red range (600 to 700 nm). At 67.5 cm distance and at 70 cm distance, the fibre hardly, but still
detected photons in this spectral range; the number of these photons, i.e. the intensity level
still lay, however, above the scotopic range (< 9 * 10 -5 µmol
