Task: Text Categorization
Input (English): In a perfect crystal this namesake intensity is proportional to the structure factor and is known as the dynamic theory of this. By collecting information from evanescent waves the limit named for this phenomenon can be surpassed to create superlenses. The radius of the aperture squared divided by the product of the wavelength and the distance to the aperture determines if the Fraunhofer or Fresnel equations for this are used. For 10 points, name this phenomenon where a wave bends around an object.
Output (English): Science
