can someone please help me with this? My homework is due in a few min I have every problem right, but I can't figure this one out. At what angle (in degrees) does first-order diffraction from layers of atoms 206.4 pm apart occur, using x rays with a wavelength of 188 pm?

OpenStudy (aaronq):

\[n \lambda=d \sin \theta \] n = diffraction order lambda = wavelength d = grating spacing theta = diffraction angle
