Question

The diffraction patterns obtained in Fresnel and Fraunhofer Diffraction are fixed in position.

(a) True

(b) False

I had been asked this question in my homework.

The above asked question is from Differences of Fresnel and Fraunhofer Diffraction in section Diffraction of Engineering Physics II

Answer 1

The correct answer is (b) False

To elaborate: The Fraunhofer Diffraction pattern is fixed in position while the Fresnel diffraction pattern moves in such a way that directly compensated the shift in the position of the object.
