Which outcome occurs when coherent laser light reflects off a butterfly wing?

💡 Explanation

Iridescence arises because the wing's layered structures cause thin-film interference, producing constructive and destructive interference patterns based on wavelength; therefore, iridescence creates shimmering colours, rather than photoluminescence or diffraction alone.
