If a sufficient amount of matter and antimatter exploded, it would
create a tremendous amount of photons, whose energy would create an
extremely powerful electromagnetic pulse. My question is, would the
heat be spread out, or all in one place? And would all the antimatter
explode at once, or would there be a time lag? And would the air
around the explosion be heated so hot so that it would create 'blue'
light?

I know this seems OT but matter-antimatter anihilation IS
electromagnetic, at least as I heard. Also, the question about blue
light due to extreme heating of the air IS an electromagnetic
question, since it involves absorbtion and emmission of photons.

Or would this be a question better suited for Quantum Physics?

First off there would be no heat until the photons were thermallized by
interacting with other matter.

Depends on the the geometry. This is same problem as any binary
explosive. If the anti-matter and matter is not well mixed then most of
it will be blown away from each other and lower your efficiency of
explosion. Of course the anti-matter would react wit hother normal
matter it is blow into and would give offits energy in over a large volume.

Blue light, violet light , red light, UV light, X-rays, Gamma Rays ...
will all be observed. I don't know how to describe a color.

Only the attraction long range attraction of matter and anti-matter is
electro-magnetic. Rest of it is pure particle physics and E=mc^2. The
blue light question would be best answered by a nuclear engineer than a
physicist.

However, if you blow away a proton and an antiproton, it should create
mesons. If you anihilate antiprotons with helium, or a heavier
substance, then you'd definately get interacting manner.

Exactly how quickly are electromagnetic waves absorbed into air? And
if you had helium, surrounding a ferroelectric container shaped just
the right way so that no matter where antimatter is placed it is
repelled by the surfaces more than it is repelled by eachother, and
around the helium you had a positive spherical or nearly spherical
shell to counteract the negative charge of the antiprotons, along with
nonconducting restraints keeping the system very steady, you could
effectively contain antimatter.

I'm hoping I might invent an antimatter engine... though I don't know
how much use it would be, as I'd also have to find a quicker way of
creating antimatter as well.

Keep it in an antijar on an antishelf.
