If a strong diffraction peak is observed when electrons are incident at an angle ` $i$ ' from the normal to the crystal planes with distance `d' between them (see figure), de Broglie wavelength $λ_{d B}$ of electrons can be calculated by the relationship $(n$ is an integer):

$2 d$ sin i $= n λ_{d B}$
$d$ cos i $= n λ_{d B}$
$d$ sin i $= n λ_{d B}$
$2 d$ cos i $= n λ_{d B}$
