To calculate the separation and the angle between the middle of the Central firing and the middle of the second bright fringe, you need to use the equation for the angular separation of two points on a diffraction pattern. The equation is:
θ = 2 arcsin (λ/d)
Where θ is the angular separation, λ is the wavelength of the light, and d is the distance between the two points.
Once you have calculated the angular separation, you can then calculate the angle between the middle of the Central firing and the middle of the second bright fringe by subtracting the angular separation from 180 degrees.
