Crystal plane
If a strong diffraction peak is observed
when electrons are incident at an
angle 'i' from the normal to the crystal
planes with distance' between them
(see figure), de Broglie wavelength AdB
of electrons can be calculated by the
relationship (n is an integer)
A. d sin i = nAdB
%3D
B. 2d cos i = NA«B
C. 2d sin i = nAdB
D. d cos i = nddB
