How does light split into colors?

[Tom.G]

Perhaps around the same time on a Sunny day, you could go outdoors and see if there is a spectrum projected on a nearby wall or anything else nearby. If so you can probable get a good idea as to where it is coming from.

Cheers,

Using the most recent photo that @YeeHaa posted:
Using the much lower distortion of that photo, I get the parallelism of the color rays as within 2.3°, well within the measurement error of being parallel.

No way.
They definitely converge closer than the horizon.

Look a the truly parallel rays of the tiles. They converge at infinity.
The light rays definitely converge within metres of the window.

The Yellow shows the vanishing point of the Red lines relatiing to the floor tiles.

Yes. That'll be the horizon, same as Omcheeto showed in post 16.
The light rays do not converge at the horizon, but much closer.
