Two rectangular glass plates (n =1.60) are in contact along one edge and areseparated along the opposite edge. Light with a wavelength of 600 nm is incident perpendicularly onto the top plate.The air between theplates acts as a thin film. Nine dark fringes and eight bright fringes areobserved from above the top plate. If the distance between the twoplates along the separated edges is increased by 600 nm, how manydark fringes will there then be across the top plate?

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.
