What is the smallest value of the incident angle in Bragg's law?
The title of my question basically is what I want to know. In Bragg's law, $nλ = 2 d \sin{\theta}$, if we want to find, let's say, $d$, and know only $\lambda$ and $n$, but not $\theta$, what could be ...

Difference between thin film interference and Bragg diffraction of electron
Thin film interference is given by:
$2d\sin\theta=n\frac{\lambda}{n_i}$,
where $d$ is the thickness of film, $\theta$ is the angle between incident light and tangent to the surface, $n$ is an integer, ...
