Refraction: rainbow. Selective reflection: flower petals. Thin-film interference: soap bubbles.
Work Step by Step
The role of refraction and internal reflection in the formation of a rainbow is discussed on pages 529-531. The role of selective reflection in making flower petals appear as they do is discussed on pages 505-506. The role of interference in explaining the iridescence of soap bubbles is discussed on pages 553-554.
