Prism Field Test

Following acoustic diagnostics, I deployed to the floor boundary near the window to assess optical phenomena. At approximately 13:40, direct sunlight intersected a faceted crystal paperweight resting on a low shelf. The refraction cast a sharp, multi-hued spectrum across the woven carpet fibres. To evaluate dispersion angles, I advanced into the beam and positioned a white plastic protractor directly within the refracted violet band. Observing the light shift across the marked increments confirmed standard refraction indices. Spatial mapping of the local light pattern is now indexed.
