Snell's Lawని ఎలా లెక్కించాలి

Snell's Law అంటే ఏమిటి?

Snell's law describes how light (or any wave) bends when it passes from one medium into another of different density. n₁ × sin(θ₁) = n₂ × sin(θ₂), where n is the refractive index and θ is the angle from the normal.

దశల వారీ గైడ్

1. 1n₁ sin θ₁ = n₂ sin θ₂
2. 2If n₂ > n₁ (denser medium), light bends toward the normal (θ₂ < θ₁)
3. 3Total internal reflection occurs when θ₁ exceeds the critical angle: sin θ_c = n₂/n₁
4. 4Refractive index: air ≈ 1.0003, water ≈ 1.33, glass ≈ 1.5, diamond ≈ 2.42
