a narrow rectangular slit AB of width d.The incident wave front disturb all parts of the slit AB simultaneously. According to Huygens theory all parts of the slit AB will become source of secondar wavelets, which all start in same phase. These wavelets spread out as rays in all directions, thus causing diffraction
To compute the intensity of the interference pattern for a single slit, we treat every point in the slit as a source of an individual Huygens wavelet, and sum the contributions of all the waves coming out at an arbitrary angle. One way to think of this is to go back to the diffraction grating case, expressed in Equation 3.3.2.
