What Is Snell's Law?
Snell's law describes how light bends as it passes from one medium to another. The refraction angles depend on the refractive indices of the media.
How is it calculated?
How Is It Calculated?
n₁ × sinθ₁ = n₂ × sinθ₂
- Enter the refractive indices of the two media and the angle of incidence.
- The refraction angle is found.
Frequently Asked Questions
Why does light refract in water?
Light travels at different speeds in media of different densities, so it changes direction (refracts).
