First of all, I don’t understand why indigo and violet are split… why not just call it purple? Ok, not my question.
Colors of the rainbow all make sense to me except purple.
Red – orange – yellow…makes sense that orange is between red and yellow, and it’s the combination of those two primary colors, nice transition
This follows with green, blue. Green is between yellow and blue.
Now… if purple aka indigo and violet are a combination of blue and red, how can it be on the opposite end of red (very different frequency) and outside the frequency range of blue? I would expect a secondary color’s frequency to be between the two primary colors that create it

You have a lot of misconceptions in your question.
First, the primary colors (of light) are red, green, and blue. Yellow is not a primary color. The reason these are primary colors are because the human eyes have these three colors of cones. Other animals have different primary colors.
Every color that you see is made by your brain. Your brain detects the relative brightness in your different cone cells and makes the colors for you.
When blue and red light are mixed, your brain makes a purple color. Like all colors, it’s not real, just something that happens in your brain.
Purple and violet are two different colors. Purple is the a mix of red and blue light (two frequencies mixed). Violet is a higher frequency than blue and triggers your red and green cones less than blue does. It’s a spectral color, that means it is just one frequency of light.
