Does this effect have a name? I’m specifically referencing the iridescent shapes to the lower left of the apple
It’s not moire…
These are Newtons rings, a different type of optical interference pattern.
It occurs when two transparent sources reflect light in contact.
You get it frequently when trying to scan transparencies using a flatbed scanner too.
Here: Newtons Rings Wikipedia
I think youre bang on with the Newtons Rings, thanks!
Amusing that this too involves an apple.
When a grid’s misaligned with another behinnd, that’s a moiré
Moire patterns do not cause a prism effect with light.
Not a direct answer to your question but the same effect can be used to measure extremely flat objects. Its a pretty cool rabbit hole.
It’s called
moiré, a form of interference pattern: ~~https://en.wikipedia.org/wiki/Moiré_pattern~~Edit: not moirè, but rather a form of diffraction grating interference because of the minute differences in distance between the two surfaces.
It is also the why DVDs and CDs have rainbow reflections.
CDs and DVDs have rainbow reflections because the “parallel” (parallel on the scale of the wavelength of light) rows of pits create a diffraction grating.
The rings in the picture are Newton’s Rings, as pointed out in comments. There are a different set of rings for each wavelength of light and since they don’t all line up you get this rainbow effect.
A swole apple with a yoyo.
I wonder if it’s a polarization effect. Look at it with polarized sunglasses on.
My first guess would be Fresnel diffraction, I guess because of the pattern
Moiré?
