Which phenomenon explains why we see a rainbow when sunlight passes through raindrops?
AReflection
BPolarization
CDiffraction
DRefraction and Dispersion
Step-by-Step Solution
  1. Step 1: Identify the phenomenon

    Rainbow formation involves bending and splitting of sunlight into colors when passing through water droplets.
  2. Step 2: Apply concepts of optics

    Refraction bends light entering and exiting raindrops; dispersion splits white light into its component colors. Reflection inside droplets also contributes but dispersion is key. Diffraction and polarization are unrelated here.
  3. Final Answer:

    Refraction and Dispersion → Option D
  4. Quick Check:

    Rainbow formation = Refraction and Dispersion ✅
Quick Trick: Rainbow = refraction + dispersion of light.
Common Mistakes:
MISTAKES
  • Confusing diffraction or reflection as cause of rainbow.
