Two rectangular plates are placed on top of one another on a table, but there is a single hair wedged between them at one end. This creates a small gap of air between the plates that acts like a thin film (with n = 1.00). Light having a wavelength of 546 nm is vertically-incident on the plates. Bright interference fringes form from the interference of the rays that reflected at the top and bottom surfaces of the air gap (these rays are shown on the picture below). The fringes have a spacing of 15.0 fringes per centimeter. What is the angle of the wedge that the h

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.
