Dispersion of Light

🎯 Learning Objectives

  • Students will be able to explain dispersion as wavelength-dependent refraction
  • Students will be able to describe Newton's prism experiments
  • Students will be able to explain rainbow formation

🧠 Core Concepts

  • wavelength_dependence
  • refractive_index_variation
  • spectrum
  • prism
  • rainbow
  • colors_of_light

📐 Formulas

n(λ) varies with wavelength
Refractive index depends on light wavelength (shorter wavelengths refract more)
Interesting Fact
Newton showed that white light can be recombined using a second prism in reverse orientation
Key Scientist
Isaac Newton
Demonstrated light dispersion with prism experiments
Philosophy
Dispersion shows that unity (white light) contains hidden diversity; it demonstrates that analysis reveals complexity underlying apparent simplicity.
