I was wondering if it is possible for there to be an anti photon or anti light? After I discovered that anti matter is real I think there could be an opposite to everything.

Since antimatter is particle physics, involve a property of mass, my un-educated guess is no.
But; (as my own thought exercise) if photons are the result of a M-AM reaction then can there be a photonic reaction that results in mass?

The classic double slit experiment has photons interacting with other photons (or even themselves) leaving a pattern of light and dark bands on the screen. The dark bands are from photons in opposite phase canceling each other out.

What happens to thier energy?

Energy is conserved--for every out-of-phase pair resulting in darkness is an in-phase pair (or singleton--photons do interact with themselves) giving double brightness. To put it another way, the quantum waveform preserves energy in the absolute sense--what we observe involves the collapsing of the waveform, repeatedly, and the observed energy is preserved in a probabilistic sense.

Actually, there are antiphotons called ''photon holes.''

I know this is too simplified but... it really is there, we just can't see it?
I know that the very nature of wave/particle duality makes it difficult to understand. In context of this thread, they don't get transformed into something else.

I mis-wrote a bit actually--

if a photon goes through, it will strike the screen somewhere. Every photon that goes through strikes the screen somewhere--so energy gets conserved.

However, no photons land in the places where they are 180 degrees out of phase, but twice as many land in the places where they are perfectly in phase, and the amplitude is somewhere in between for in-between the two extremes. In any case, what you see is the bright and dark bands. So, this is as close as we get to two photons annihilating each other.

Note, every photon will land in a bright or dark band according to probability determined by the interference of waves, even if you send only individual photons. Cover one slit, and the interference doesn't happen anymore and individual photons just go directly opposite the slit. This proves that even single photons go through both slits at once.

So--I did miswrite--energy is conserved period, not just probabilistically. It is also conserved in the wave-form sense, but that can't be directly observed, just inferred from the various experiments.

Waht's the opposite of light? Dark.

Ummm you sure I thought dark is just the absence light. I don't see that as the opposite of light.

Yep, darkness is the absence of light.
As Dhd40 said, photons show characteristics that set them apart from particles and waves- though they have no mass. Anti-photons would have to be anti- energy or the opposite of energy(Not the absence of energy) which I'm not sure what state that would be.


Too much time travel reading will have you contemplating negative energies...

Anti-matter also shows opposite electrical charges.

Oh I forgot to compliment you on the new pic or old pic I haven't been here for a while. What r photons?? I thought I knew but I dont think I do.

I fall back on good ol' wikipedia.

the first sentence on wiki says it is the elementary particle you say its not a particle at all. Who should I believe?

What's the opposite of serious? A joke. Hence the smiley. Or was it too dark to see it?

It's both, thats the weird thing about it.
hmm.. I always thought the anti-particle of light was what stopped it from slipping into negetive energy levels, in Durac sea kind of way.

Yes. Vacuum energy/ particle flux.
