Δa_r = 0,00708402 mm²
Δa_r1 = 0,0071 mm²
Δa₂ = 0,008 mm²

$$\frac{0,008 - 0,00708402}{0,00708402} > 0,1$$

Δa_r = 0,0071
a_r = 0,485 ± 0,0023

λ = 589,6 nm
λ = 589,6 * 10^-6 mm

$$R = \ \frac{a_{r}}{\text{λ\ }}$$

$R = \ \frac{0,485}{{589,6*10}^{- 6}} = 822,591\ mm$

R = 0,822591 10^-3 [m]

$$\frac{\Delta R}{\text{R\ }} = \ \left| \frac{\Delta a_{r}}{a_{r}}\ \right| + \ \left| \frac{\Delta\lambda}{\lambda} \right|$$

$$\Delta R = \ \left( \left| \frac{0,0071}{0,485} \right| + \ \left| \frac{0}{{589,6*10}^{- 6}} \right| \right)*0,822591$$

ΔR₁ = 1,013 mm

$$\frac{0,013 - 0,012042053}{0,0120042053} < 0,1$$

ΔR₁ = 1,013 mm
R = 0,823 * 10^-3

R= 0,823 * 10^-3 ± 0,013 [m]
