2. The Physics of Water Droplets: From Raindrops to Rainbow Formation

a. How water droplets form and behave in the atmosphere

Water droplets originate in the atmosphere through processes like evaporation and condensation. When water vapor cools, it condenses onto tiny particles called aerosols, forming droplets typically ranging from 0.1 to 5 millimeters in diameter. Their behavior—whether falling as rain or suspended as mist—is dictated by gravity, air currents, and droplet size.

b. The optical properties of water droplets that create rainbows

Rainbows occur when sunlight interacts with water droplets, acting as tiny prisms. Light entering a droplet refracts, reflects off the inside surface, and refracts again as it exits. This process disperses light into its spectrum of colors. The angle of refraction—typically around 42 degrees—determines the rainbow’s position in the sky, creating the iconic multicolored arc.

c. The role of droplet size and shape in visual phenomena

The size and shape of water droplets influence the appearance of rainbows and other optical effects. Larger droplets produce more vivid and well-defined rainbows, while smaller ones lead to diffuse or supernumerary rainbows. The spherical shape ensures consistent refraction angles, but irregular shapes can cause distortions, impacting visual phenomena in both natural and urban settings.
