Formulas and Key Relations

1. Refraction and Snell's Law

sin i / sin r = constant (n)

n1 sin i = n2 sin r

n = c / v

1n2 = v1 / v2 = n2 / n1

n = A + B/λ² + C/λ⁴ + ...

2. Relative Refractive Index and Wavelength Dependence

1n2 = n2 / n1

3. Reversibility of Light and Parallel-Sided Slab

i = e

RM = t sin(i − r1) sec r1

1n2 × 2n1 = 1

4. Real Depth, Apparent Depth, and Normal Displacement

n = AO / AI = real depth / apparent depth

d = t(1 − 1/n)

d_app = d1/n1 + d2/n2 + d3/n3 + ...

n = (d1 + d2 + d3 + ...) / (d1/n1 + d2/n2 + d3/n3 + ... )
