A person makes two long, parallel knife cuts in a piece of cardboard. She then shines coherent light through the cuts (slits) towards a white sheet. The slits are 0.200 mm apart. The light passes through the slits and hits the sheet, which is placed 5.00 m away. This makes an interference pattern whose bright areas are 1.58 cm apart from each other.

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.
