Question

Write all formulas of refractive index.

Answer 1

Explanation:

Formula 1 - Snell's Law. n 1 × sin(θ 1) = n 2 × sin(θ2)

Formula 2 - Numerical Aperture. NA (numerical aperture) = n × sin(θ)

Formula 3 - Refractive Index (or Index of Refraction) n = c/η

Answer 2

Answer:

1. Figure 1 - Refraction of Light.
2. Formula 1 - Snell's Law. n 1 × sin(θ 1) = n 2 × sin(θ2)
3. Formula 2 - Numerical Aperture. NA (numerical aperture) = n × sin(θ)
4. Formula 3 - Refractive Index (or Index of Refraction) n = c/η
