Fogbows form when sunlight shines through tiny fog droplets less than 0.1 mm wide.
These minuscule droplets cause strong diffraction, spreading light into broad, pale bands.
Unlike rainbows, fogbows lack vivid colors and appear mostly white or faintly bluish.
Their arcs are wider and often larger in diameter due to smaller scattering angles.
You’ll see them opposite the sun, usually near mountains, coasts, or early-morning valleys.
Fogbows sometimes show a subtle red outer edge and blue inner edge under ideal conditions.
They vanish quickly as droplet size increases or sunlight intensifies during the day.
Photographers use polarizing filters to enhance contrast between fogbow and mist background.
Meteorologists study fogbow visibility to infer droplet size distribution in low clouds.
This phenomenon reminds us how subtle changes in nature reveal deep optical principles.
