Anti-reflective coatings on camera lenses and glasses work by utilizing thin-film interference to greatly reduce reflected light. (Ever wondered why your glasses have a bluish/magenta tint when they reflect light? It's from that thin film!) We wish to coat flat glass (n=1.50) with a transparent material (n=1.25), so that reflection of light at wavelength 402.375nm is eliminated by interference. What is the minimum thickness (nm) of the coating that will work for our purposes?

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.
