How is it not a rainbow? It's a multi-colored band from red to blue in the shape of a bow. What criteria does it not fulfill?

Liquid and solid water actually have almost identical density and refractive index. Both are very slightly lower for ice, while both are quite a bit higher for glass. So liquid water is actually closer to glass than ice is, meaning it's actually easier to make a rainbow with liquid water than with ice.
Also, there's no such thing as "dispersion index" in the context of optics.

And yes, I did make water almost like a prism. Guess what? That's what happens in nature! Raindrops almost act like tiny little prisms.

mmmm

ice is a solid, rain or tap water is a liquid/fluid..
thanks for trying, but still waiting for video of WATER and light

Oh, just re-read one of your quotes and saw this gem:

I'm guessing this was before you googled "dispersion of light" and realized dispersion is CAUSED by refraction. Also, the frequency of light does not change.

but you just refered to dispersion wrong today , i guess you read google and now you think your an expert.

and there's no such thing as "dispersive qualities" with regards to light.

Moving the goal posts again rofl.
You just can't help yourself can you

i already proved he shifted the goalposts on the challenge, try to keep up ok?

if you say there is no difference, then make a rainbow indoors with just some drops of water and a light source, but be prepared to fail.

"dispersion index"

i already explained the is no dispersion index like there is a refractive index - so the question is moot.

Keep dodging those things you promised, gg faker.

first of all thats not really a rainbow - its like a retarded refrected spectrum - still not enough dispersion to create a rainbow
secondly - a few drops of water ≠ a block of ice , they have different refraction and dispersion indexes as well as different densities - all you did was make water almost like a prism

but nice try at moving the goalposts again, typical dishonesty

they have different refraction and dispersion indexes as well as different densities
