Do you think that's what Jonte meant? I don't. aerocontrols Send a noteboard - 12/05/2019 10:54:40 PM

I think he understands physics better than that. I think a photon with the properties Shrike describes will produce 'green' light independent of the medium through which that photon travels.

Perhaps he knows more than I, though. It's not really my field. Roland's observations about optical illusions aren't really relevant.

If Jonte means something like "Sunlight loses red wavelengths and shifts to blue as you get deeper in the ocean", then that has nothing to do with light itself changing, and instead has to do with the water and particulates filtering out some colors while others continue on. 'Red' and 'Blue' don't change - blue pierces the water better and red is blocked. "What is red" does NOT depend on that medium.

If he means that an observer who is travelling away from the light source at relativistic speeds may see a shift in color, that again has nothing to do with the medium.

Hollywood has the best moral compass, because it has compassion.

Ah. Sorry I missed it. Or possibly not that sorry, I've really seen too many debates about that. *NM* Legolas - 09/05/2019 09:03:31 PM 217 Views

The Soviets were totally communists even if they didn't achieve communism. Tom - 19/05/2019 05:07:28 PM 422 Views
Socialism is the takeover of the means of production by the "people" (in practice, the state). Tom - 19/05/2019 05:06:19 PM 435 Views
