Answer:
[tex]\theta= sin^{-1}(\frac{\lambda}{a})[/tex]
Explanation:
Assuming we have to find
Find the angle theta to the first minimum from the center of the central maximum (Expressing answer in terms of λ and a.):
a= avg separation between the building.
λ = wavelength
for single slit diffraction we have
a sinθ =nλ
for the first minimum n=1
a sinθ =λ
therefore,
[tex]\theta= sin^{-1}(\frac{\lambda}{a})[/tex]
