Svetlobi se lahko spremeni valovna dolžina, ko le-ta preide uklonsko mrežico. Ali se ji in koliko se ji spremeni valovna dolžina, še ni izmerjeno in dokumentirano, čeprav ta meritev posega v temelje fizike. Meritev predstavlja belo liso v naboru fizikalnih meritev.

The wavelength of light can be changed as it passes the diffraction grating. Whether and how its wavelength changes is not yet measured and documented, although this measurement may solidify the foundations of physics. The measurement represents a white spot in a physical measurement.
