g How many diffraction maxima are contained in a region of the Fraunhofer single-slit pattern, subtending an angle of 2.12°, for a slit width of 0.110 mm, using light of wavelength 582 nm?

2

Explanation:

We know that in the Fraunhofer single-slit pattern,

maxima is given by

Given values

θ=2.12°

slit width a= 0.110 mm.

wavelength λ= 582 nm

Now plugging values to calculate N we get

Solving the above equation we get

we N= 2.313≅ 2
