# Diffraction and Huygens sources

Hello,

I'm pondering on why bending occurs most when the width of the aperture is close to the wavelength of the propagating wave. According to Huygen's principle, should'nt there be point sources around the edges of an aperture regardless of the width and thus the bending propagate to infinity at even the sharpest angles due to the semicircle of propagation of the point source?
