To determine the width of a slit in a piece of paper you mount the paper a distance R 0.6 m from a screen and illuminate it from behind with laser light of wavelengtha= 638 nm. The picture shows a distance of x= 8 mm between two of the intensity minima. Calculate the width of the slit (in um = 106 m).

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.
