Question

6. What is the diffreence between Frensel’s diffraction and  Fraunhofer diffraction ?​

Answer 1

But the difference between Fraunhofer and Fresnel diffraction is dependent on how you setup your experiment. Fraunhofer diffraction: Light can occur as plane waves, which we can imagine as the waves that come rolling in over the ocean. ... A point source of light produces spherical waves.

Answer 2

★★HOLA MATE★★

THIS IS YOUR ANSWER.

FRENSEL DIFFRACTION, OR A NEAR-FIELD DIFFRACTION, OCCURS WHEN A WAVE PASSES VIA A SMALL HOLE AND DIFFRACTS, CREATING A DIFFRACTION PATTERN. THE SIZE OF THE PATTERN DEPENDS ON THE DISTANCE BETWEEN A PROJECTION AND AN APETURE... DIFFRACTED WAVES BECOME PLANER WHEN THE DISTANCR OF PROPOGATION IS INCREASED.

I HOPE MY ANSWEE HELP YOU TO COMPHREHEN CONCEPT.
