Shadows of pine trees are evident in the lunar reflection off of a puddle of water. A drop of oil spread across the water’s surface reflects a rainbow of colors, due to thin film interference from the oil layer. Each color, i.e., wavelength, is observed—due to constructive interference—at a particular angle relative to the lunar reflection, thereby creating a circular pattern. A second droplet hitting the surface creates ripples. Concentric circles are formed as the waves propagate outward, and as they continue moving outward the amplitude of each slowly decreases.
