📍 Click and drag the light source to move it anywhere (above or below the boundary)
🔵 Blue region = Medium 1 (Top) | 🟦 Dark blue region = Medium 2 (Bottom)
💡 Move the source below the boundary to see total internal reflection!
Snell's Law: n₁ sin(θ₁) = n₂ sin(θ₂)
Angle of Incidence: 0°
Angle of Refraction: 0°
Note: Total internal reflection occurs when light travels from denser to lighter medium at angles greater than the critical angle.
