If the sun put out nothing except EM waves, what
would a comet's tail look like? I suggest you
read Eugene Hecht's section in "Optics" titled:
"3.3.4 Radiation Pressure and Momentum" in my
4th edition.

You cut off the first line of my post, "Do you know that the sun puts out a
lot of neutrons and other particles?" I didn't say the sun puts out nothing
except EM waves.

I am asking you: What if the sun put out nothing except
EM waves. Would comets still have a tail or not?

Are you talking about the ion tail or the dust tail? The dust tail is
affected by EM; but the ion tail is affected only by magnetic forces.

So a large part of the visible tail of the comet would
still point away from the sun even if the sun emitted
nothing but EM waves. EM waves possess momentum, apply
radiation pressure to dust particles (matter), and have
relativistic mass.

That is correct.
