Question

derive the fraunhafer diffraction
​

Answer 1

Explanation:

Fraunhofer diffraction at single slit. ... This is due to the diffraction of light at slit AB. It is observed that, the intensity of central maxima is maximum and intensity of secondary maxima decreases as the distance from the central maxima increases. The width of central maxima is double, than that of secondary maxim....

Fraunhofer diffraction is the type of diffraction that occurs in the limit of small Fresnel number . In Fraunhofer diffraction, the diffraction pattern is independent of the distance to the screen, depending only on the angles to the screen from the aperture.
