WebbAdd to collection. Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light. Webbthe beam, diffraction at the edge of the lense is of no relevance. Focusing the beam leads to a characteristic waist, which is refered to as the beam focus. Knowing the parameters of the primary beam given in equations (1) and (2) is necessary to calculate the secondary beam properties. even if the rayleigh length
