The intensity in a Fraunhofer diffraction pattern for a single slit is given by the equation
I=
2
sin
θ
2
θ
, where
θ=
πbX
λd
,
λ
is the wavelength of light,
d
is the distance of the diffracting slit from the screen,
b
is the width of the diffracting slit, and
X
is the range of the diffracting pattern on the screen from the center of the space between the edges of the geometrical shadow. The intensity of the pattern is given in arbitrary units.
