Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.

Question

A double-slit system with individual slit widths of 0.030 mm
and a slit separation of 0.18 mm is illuminated with 500 nm light directed

first-order minima of the diffraction pattern? (Do not count the
fringes that coincide with the minima of the diffraction pattern.)
