Refraction Using Huygens Principle
The plane wave is bending toward the normal as it enters the denser medium (n₂ > n₁). According to Huygens' principle, each point on the wavefront acts as a source of secondary wavelets.
Key Formulas:
Snell's Law: n₁sin(i) = n₂sin(r)
Speed ratio: v₂/v₁ = n₁/n₂
Wavelength ratio: λ₂/λ₁ = v₂/v₁
Huygens' principle: Each point on a wavefront is a source of secondary wavelets
