Bragg's Law and Diffraction

This simulation was created due to request from user: Bragg's Law and Diffraction

Initialize: $2*d \sin(\theta)= \lambda$ ;
You can adjust $d$ , $\theta$ and $\lambda$ (wavelength)
And you will find the outgoing waves only in phase at particular angle which satisfy
$2*d \sin(\theta)= n*\lambda$
