For the first dark ring, the m value is, m = 1.22
Diameter of the pinhole, d = 0.1 × 10-3m, wavelength, λ = 632.8 × 10-9 m
Part A: At what angle θ1 to the normal would the first dark ring be observed?
Part B: Suppose that the light from the pinhole projects onto a screen 3 meters away. What is the radius of the first dark ring on that screen? Notice that the angle from Part A is small enough that sinθ≈tanθ .
Part C: The first dark ring forms the boundary for the bright Airy disk at the center of the diffraction pattern. What is the area A of the Airy disk on the screen from Part B? answer must be in mm2
