Which outcome occurs when ambient light reflects off closely spaced reflective layers?

💡 Explanation

Iridescence occurs because light undergoes thin-film interference at the interfaces of the reflective layers. Constructive and destructive interference changes with viewing angle, therefore different colors are observed, rather than uniform reflection without interference.
