What is the variation in the pattern observed for single slit Fresnel diffraction than single slit Fraunhofer Diffraction?

Correct Answer: The region of minimum intensity is not completely dark
The diffraction pattern due to the single slit Fresnel Diffraction is similar to single slit Fraunhofer Diffraction, except the regions of minimum intensity are not completely dark. This is so because there is never a complete destructive interference in Fresnel Diffraction.
