again it is a projection of the surface then

That's literally cheating

you don't NEED water to create a rainbow.

you need a material that refracts light.

was the goal to specifically use water?

Is that so? Then do it without a CD.

the rainbow should be the light in the medium being refracted, not due to the coloration of the medium

ivo, how is it being colorized?

the foil in the CD is layered so you can burn it,

there is color involved in that

it's colorizing by refracting standard light to create colors.

the foil is not a single layer medium, you use multiple mediums, and it is not refraction it is reflection of the medium

greetings, flatties

if it were straight up reflection, it would reflect white light. the light is being refracted into its colors.

and then reflecting the rainbow.

it's the same thing.

a rainbow is created by passing through a medium, and by breaking up in speed due to angles, this creates the colorbands, when you use a cd it can take thee color which is in the foil

If it's the same thing then you should be able to do it without that CD, no?

Do it and stop bitching about how it satisfies the argument. Which it does not.

when you mean without a CD, Nomad, what are you suggesting?

actually a rainbow is created by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky.

and it is the water droplets that are refracting the light.

similarily, the disc material is refracting light.

i mirror obviously wouldn't work because it doesn't refract light.

So you should be able to make a rainbow indoors with no outside interference using only light and water.

rainbows are actually 4th grade knowledge guys come on

so, the goal, then, is to specifically make a rainbow with *water*.

indoors?

Light and water is what you have.

Indoors.

Yes.

Ok, well, I suppose I can't test that at the moment.

i found a video of a person making a rainbow indoors

oh, noice

@eletrick33 you sure about that ?

Using only light and water? 🤔

yeah theres a million videos on how to do it this is just a random one i picked https://youtu.be/vXccpwytjL8

cause you can have rainbows which move with you and are full circles even when you are close to it, i have seen rainbows in full circle at 5 meters altitude move with me while i drove past it, it has a relation to your eye as well, no 4th grade stuff there,

So she didn’t just use light and water. Okay.

Irrelevant video to the topic at hand then.

I think I missed why this was important. What's the relevance to only making a rainbow indoors with lighting and water?
