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.
again - its moving the goalpost - your challenge was to make a rainbow with water and light , not ice and light. If ice is the key to a rainbow - why is the arctic not a constant rainow - lots of ice there...
your so dishonest. And if your calling that a rainbow, then either your camera of your eyes are broken
