Arggg, I think I am getting dumb. I can't reallly understand the whole thing about photon, the electric wave and magnetic wave. LOL.
The problem is, when I view light as particle, when it doesn't need a medium. But to imagine light particle shooting here and there is kind of wierd. If sun is shooting light particles, that means matters can be turned into light? Like we convert electricity
and whatever inside the light bulb to light? I kind of thought light is just a vibration, nothing more.
And then, if I view light as wave, which would requires a medium to exist, like sound needs air. But then, we consider it can travel in a total void vacum space. Wouldn't electric wave and magnetic wave requires some kind of medium as well? What if we just
haven't find the medium for those waves? Or wave can exist without any medium?
I guess I have to reinvestigate wave. Maybe my interpretation of wave is wrong.

That's exactly what E=mc2 means. Matter and energy are interchangeable and that is the relationship between them.
To be clear, light is NEITHER particle or wave, but a wave particle duality. It only becomes one or the other when we look at it, and which depends on how we look at it.
