Difference Between Fresnel Diffraction And Fraunhofer Diffraction


Fresnel diffraction Fraunhofer diffraction
The source and the screen are at finite distance from the diffracting aperture The source and the screen are at infinite distance from the diffracting aperture
For obtaining fresnel diffraction , zone plates are used For this single double ae plane diffraction grating are used
The wavefronts are divergent either spherical and cylindrical The wavefronts are plane which is released by using convex lens
No mirror or lenses are used for observation Diffracted light is collected by lens as in telescope
