Manufacturers of wire (and other objects of smalldimension) sometimes use a laser to continually monitor thethickness of the product.The wire intercepts the laser beam, producinga diffraction pattern like that of a single slit of the samewidth as the wire diameter. Suppose a helium –neonlaser, of wavelength 632.8 nm, illuminates a wire, and the diffractionpattern appears on a screen at distance L = 2.60 m. If thedesired wire diameter is 1.37 mm, what is the observed distancebetween the two tenth-order minima (one on each side of thecentral maximum)?

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.
