Question 4 Read the following problem, then watch video solution Boomer 's Principle, then try to solve this problem. Babinet's principle allows one to determine the diffraction from an obstacle if you know the diffraction from an opening ofthe same shape. It follows from the principle of superposition and the linearity of Maxwell's Equations. Consider an incident field E}. The field diffracted from an aperture A is EA. Then, the eld diffracted from a similarly shaped obstacle sf is E; = E, EA. All the fields must be evaluated in the same place, e.g. the final screen. Using Babinet 's principle1 determine the farfield interferencefdif fraction pattern {i.e the irradiance, not field] created by a plane wave diffracted by a single strand of human hair {width 5t] microns}. a} WI is the field after a single slit of the same width as the hair? b} What is the field after the hair? c} lulu-mat is the intensity pattern after the hair
