PeterDonis replied to the thread Undergrad How can light be a wave and particle at the same time?.It depends on what you want to use the term "light" to refer to. That's a question about words, not physics. I was, of course, using it... -
PeterDonis replied to the thread Undergrad How can light be a wave and particle at the same time?.To the extent it's offering something, the issues with what it's offering have already been pointed out. Again, either way the issue is...

PeterDonis replied to the thread Undergrad How can light be a wave and particle at the same time?.Which is a perfectly reasonable reading since it's what the thread title actually says, word for word. :wink: I'm not sure I see the...

Like.
The electron and the photon are particles, by definition. They are defined by their generic properties, as per the standard model of... -
PeterDonis replied to the thread Undergrad How can light be a wave and particle at the same time?.No, they're not... Yes, but a quantum field is not a wave. It's a quantum field. Your next sentence contradicts this: Yes, and it's...

PeterDonis replied to the thread Undergrad Why did the photon lose its license?.Neither of these are correct. What is correct is that "proper time" and "proper distance" are undefined for light. Lightlike objects in...

PeterDonis replied to the thread Is the quantum wave function a real object or a mathematical tool?.For the MWI, yes, the wave function is the fundamental reality, everything else is emergent. However, I don't think that's true for the...
