why purple is on the end of the rainbow/color spectrum

925 views

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

Light is a spectrum of low energy to high energy. Radio waves to gamma waves. Visible light makes up a small portion of the light spectrum.

When you see a colour from a paint or a you’re seeing the colour that is reflected back at you as the molecules in the paint absorb all other colours apart from that one.

When you see a rainbow or a colour spectrum light, it is being split into its constituent parts based on how much they bend in the medium the light is travelling through. High energy light like blue and violet light bends more compared to low energy light like red light. This is why rainbows form.
