My study of wave-particle-duality of light, as described in a paper: “Proposed explanations for thewave-particle duality of light and double-slit interference of single photons” (Tank, H. K. http://vixra.org/pdf/1407.0036v2.pdf) leads to new light about the true nature of ‘light’; that: (i) either the real wavelengths and frequencies of the ‘waves’ of ‘light’ are not what we have been thinking so far; or (ii) the rate of formation of ‘particles’ called ‘photons’ is at much slower rate than the frequency of the waves. It was found in the above-cited paper that if light is both ‘wave’ as well as ‘particle’, then a photon should contain a wide ‘band’ of waves, rather than a single frequency; and whenever and wherever all the spectral components of the wide band get constructively added a ‘particle’ gets formed. The wavelengths and frequencies of the actual band of waves, and the ‘distances’ and ‘time-rate’ of successive formations of ‘particle’ are two different phenomena. Therefore, (i) if the wavelength of the wave measured by us is ‘distance’ between two successive formations of ‘particles’ then the frequency of the actual wave may be much higher; or (ii) if the wavelength measured by us is wavelength of the actual wave, then the formation of ‘particles’ called ‘photons’ may be at much slower rate than the frequency of the wave.. If we can establish perfect relation between wavelengths of the band of waves, and ‘distance’ between successive formations of ‘particles’, then it may be possible to make deterministic prediction of detection of ‘photons’.
