Fórmula
Snell's Law
Snell's law describes how light bends when passing between media with different refractive indices.
Formula
n1 * sin(theta1) = n2 * sin(theta2)
Light bends toward the normal when entering a denser medium (higher n) and away from the normal when entering a less dense medium.
Ejemplo Resuelto
Light enters glass (n=1.5) from air (n=1) at 30 degrees.
- 01n1*sin(theta1) = n2*sin(theta2)
- 021*sin(30°) = 1.5*sin(theta2)
- 030.5 = 1.5*sin(theta2)
- 04sin(theta2) = 0.333
- 05theta2 = 19.47°
Preguntas Frecuentes
What is the refractive index?
The ratio of the speed of light in vacuum to the speed of light in the material. Air: ~1.0003, water: 1.33, glass: 1.5, diamond: 2.42.
What causes a rainbow?
Sunlight refracts when entering water droplets, disperses by wavelength (Snell's law gives different angles for different colors), and refracts again on exit.
What happens when light goes from dense to less dense?
The refracted angle is larger than the incident angle. Above a critical angle, total internal reflection occurs.
