In a 2-slit experiment, one of the slits is covered by a thin film of refractive index n1 and the other slit is covered by another thin film of refractive index n2 (n1>n2). Both films have the same thickness t. A flat screen is located a distance L from the slits. The slit spacing is d. Find the shift in the position of the central maximum of the interference pattern because of the presence of the thin films.

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.
