Thus, the phase difference at point Pis φ=dsinθ/λ= 0.397 wavelengths, which means it is between the central maximum (zero wavelength difference) and the first minimum ( 12wavelength difference). Note that the above computation could have been simplified somewhat by avoiding the explicit use of the tangent and sine functions and making use of the small-angle approximation (tan
