Rainbows
Nature's Spectacular Light Show
Introduction
• • A rainbow is a natural phenomenon caused
by reflection, refraction, and dispersion of
light in water droplets.
• • Appears as a multicolored circular arc in the
sky.
Formation of Rainbows
• • Sunlight enters a raindrop and bends
(refraction).
• • Light reflects off the inside surface of the
drop.
• • Light bends again as it exits, spreading into
colors.
Colors of the Rainbow
• • Traditional sequence: Red, Orange, Yellow,
Green, Blue, Indigo, Violet (ROYGBIV).
• • Order is due to different wavelengths of
light.
Types of Rainbows
• • Primary rainbow – brightest, outer edge red,
inner edge violet.
• • Secondary rainbow – fainter, with reversed
color order.
• • Other forms: supernumerary rainbows,
fogbows, moonbows.
Rainbows in Culture and Science
• • Symbol of hope, peace, and diversity in
many cultures.
• • Studied in physics and meteorology for
understanding optics.
Conclusion
• • Rainbows are a beautiful intersection of
science and art in nature.
• • They remind us of the wonders of light and
atmosphere.
