A wavefront is

Wavefronts

Consider the following statements A and B and identify the correct answer. A. Fresnel's diffraction pattern occurs when the source of light or the screen on which the diffraction pattern is seen or when both are the finite distance from the aperture. B. Diffracted light can be used to estimate the helical structure of nuclei acids.

In Fresnel diffraction, if the distance between the disc and the screen is decreased, the intensity of central bright spot will
