Diffraction Conditions
Fraunhofer diffraction
Bragg diffraction
For constructive interference,
d
sin
f
=
n
l
For constructive interference,
2(
d
sin
q
) =
n
l
In Fraunhofer diffraction, the diffraction equation is d sin
f
= n
l
.
In Bragg diffraction, a similar diffraction equation results, 2 (d sin
q
) = n
l
.
