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

Write down the interference condition for a thin film shown in the figure. It should be noted here
that reflected light will experience a 180 degree phase change when it reflects from a medium of higher
index of refraction and no phase change when it reflects from a medium of smaller index.
