Interference Patterns: Fente and Peigne Convolution

This lecture discusses the relationship between the width A and distance D of a system with six slits, analyzing interference patterns. By reconstructing the interference figure from the given data, it shows how the convolution of two known systems leads to the system in question. It explains the interference patterns produced by six negligible width slits and a single slit of width A, highlighting the differences in the number of minor peaks. The lecture demonstrates how the interference pattern resulting from the convolution is the pointwise product of the individual interference patterns. By analyzing the distances between peaks and minima, it derives the relationship D = 4A, providing a practical example with micrometer measurements.
