The presence of fringes suggests the phenomenon of interference, which is produced by the double slit. However, the fringes are not equally spaced and have varying intensities, indicating that diffraction also plays a role. Therefore, the fringes result from the combination of interference from the double slit and diffraction from the two slits.
