Total Internal Reflection
41 words 1 min Modified
- A special case of Internal Refraction in which Snell’s Law cannot be physically satisfied
- This is because $\theta_2$ is capped at $\frac{\pi}{2}$ rad, so beyond some critical $\theta_{c} \coloneqq \sin^{-1} \frac{n_{2}}{n_{1}}$, the planar boundary is treated like a normal reflecting surface
