Your along the right lines. In dealing with the wave particle duality theory, it helps to look at it through a different perspective. On a deeper level everything Is based on Vibrational frequecies. Energy Vibrates at a higher frequency where as Matter is a much slower, denser frequency. That also brings into effect the law of conservation of Mass/Energy & E=MC^2(Energy = Mass times the speed of light squared) This means that by speeding up the vibration of Matter times the speed of light squared, it becomes energy. This is why we have wave particle duality because they are in essence the same thing. Its like a Frequency scale with matter on one side and energy on the other. I don't know if that helps

: Does light have mass??? Of corse not? However I was thinking about the hizen-burg (I'm not a good speller) : wave-particle relation. : For example an apple has mass and wave properties. We see the particle side more than the wave side but it is there. An electron has mass and paritle nature. We see mostly the wave side. : My point is that a photon behaves like a particle and a wave. Maybe a photon has mass but so little we can't detect it.....Maybe not. : Does any one know of the sure test that proved without a shadow of a dought that a photon has no mass. : Or does it relate to the zero rest mass and apparnt : mass with its velocity....
