d* sin(φ) =
d* sin(φ) = $$d\cdot sin(\phi)$$ = $$\frac{(2\cdot k+1)\cdot \lambda}{2}$$ d* sin(φ) = k* λ+ $$d\cdot sin(\phi)$$ = $$k\cdot \lambda+\frac{\lambda}{2}$$ d = $$d$$ = $$\frac{k\cdot \lambda+\frac{\lambda}{2}}{sin(\phi)}$$ d = + $$d$$ = $$\frac{k\cdot \lambda}{sin(\phi)}+\frac{0.5\cdot \lambda}{sin(\phi)}$$
