1. The name most often associated with emission theory is Isaac Newton. 2. Instead, Majorana detected wavelength changes inconsistent with emission theory . 3. This has come to be known as " emission theory ". 4. In addition, Emission theory might fail the Ives Stilwell experiment, but Fox questioned that as well. 5. Plato first articulated the emission theory , the idea that visual perception is accomplished by rays emitted by the eyes. 6. Emission theory asserts that Doppler shifting of light from a moving source represents a frequency shift with no shift in wavelength.7. Albert Einstein is supposed to have worked on his own emission theory before abandoning it in favor of his special theory of relativity. 8. Most argue that Euclid's version of emission theory was purely metaphorical, highlighting only the geometrical relations between eyes and objects. 9. The "'emission theory of sight "'seemed to be corroborated by geometry and was reinforced by Robert Grosseteste. 10. In 2004, Alberto Mart�nez examined the rejection of Ritz's emission theory in favor of special relativity from a historical perspective.
