Does this effect have a name? I'm specifically referencing the iridescent shapes to the lower left of the apple

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.
