here theta is defined as the angle with the surface normal, not with the surface plane, hence nlambda = 2 d cos(theta) . Furthermore this video is one of the worst explanations of XRD that I can imagine.

@TheSergeZebian Yeah, Bragg's law is nLamba=2dsin(theta), not cos(theta).

thanks (:
but one question, ive seen the formula represented as 2dsin(theta) - why sine?
i understand the cosine much better as it is the perpendicular line (adjacent) and the line that is coming in (hypotenuse)
