  6. Oct 22, 2023 · Renowned researchers Thomas Young and Hermann von Helmholtz contributed to the trichromatic theory. The theory began when Young sided with the unpopular theory that light traveled in the form of a wave, and he calculated the wavelength of each color in the visible light spectrum.

  7. Helmholtz's extensive research findings and theories. His research in the physics of sound as well as his place theory of hearing led to refinements by Georg von Bekesy that gained him the Nobel Prize in 1961. Apparently, Helmholtz opposed the idea of the necessity for an experimental psychology

  8. This article outlines the life and career of Hermann von Helmholtz in order to illuminate his influence on the nascent social sciences, above all on psychology.
