Which phenomenon causes iridescent colors on soap bubbles?

💡 Explanation

Thin-film interference causes iridescent colors because light waves reflecting from different bubble interfaces interfere constructively and destructively. Therefore, certain wavelengths are enhanced, rather than colors separating via refraction processes.
