But a change in the speed of a light wave would affect its frequency.Are you sure? Can you explain a rainbow to me? All wavelengths seem to be created by same photons going the same speed through the same density medium.

is there something on those links about light changing speed?
Can you explain a rainbow to me? All wavelengths seem to be created by same photons going the same speed through the same density medium.Yes, scientists can answer this. You can look this up for youself. Why are you even asking this?
A better question is, can those who posit miracles answer this? If you are a “miracle-ist,” then why would you be committed to the velocity of light in a vacuum being constant or that photons have wavelengths? Why even posit the existence of photons at all? Why not just posit that science is merely a collection of useful regularities with many potential exceptions? By this way of thinking, the theory of photons just makes useful predictions – but photons don’t exist.
How can theists explain rainbows? Easy. God simply said “Let there be a rainbow,” and so it was. There might be a chain of material cause and effect behind this, or not. There is no necessary link between cause and effect for the miracle-ist.
Why did god will this particular rainbow? It’s none of our business! If we, ourselves, cannot will a rainbow into existence, then we are not allowed to even ask this querstion. To borrow a phrase for constitutional law that Job would have found familiar, we have no “standing” in the matter.

A rainbow is a wonderment to be admired and respected. A rainbow is like a butterfly. It's sacred and not something to be taken apart, as is done - with anything that moves - in testing labs, just to satisfy curiosity.
Science and religion, like oil and water, do not mix well.
Science and religion, like oil and water, do not mix well.Dogmatically latching on to ideas in either one can lead to heresy, apostasy and blasphemy, and not in just the religious sense.
Religion can claim knowledge of who did what; science can claim knowledge of how it was done. Knowledge of what precedes knowledge of how.
is there something on those links about light changing speed?Yes.
The first sentence in the second link is:
“In optics, the refractive index or index of refraction of a material is a dimensionless number that describes how fast light travels through the material.”
A dimensionless number? What is that?

A rainbow is a wonderment to be admired and respected. A rainbow is like a butterfly. Because we are curious by nature, we "take apart" rainbows and butterflies to see what makes them tick. But no matter how much we learn about butterflies and rainbows, there is always something more to learn about them. And yet, for all that we do/will know about rainbows and butterflies, our wonderment for them remains undiminished.

So would that be any possible number, just that we can never know what it is?How about 1? Do you know what it is?

A theoretical relative (variable) value?
A dimensionless number? What is that?Usually, a ratio. Surely you can look up what a ratio is.
