Fresnel diffraction

Interference of secondary spherical waves

There are two teachers, Fresnel and Fraunhofer, who explained the phenomenon of diffraction. Fresnel explained this diffraction by considering the mutual interference of secondary spherical waves based on Huygens' principle, which is why it is also called the Huygens-Fresnel principle. "Each point on the wavefront at a given time acts as a source of secondary spherical waves, and the amplitude of the secondary waves decreases as the angle of inclination between the direction of the primary wave and the secondary wave increases, reaching a maximum when both waves are directed in the same direction and a minimum when they are directed in opposite directions. These phenomena arise from the mutual interference of the secondary spherical waves." *For more details, please refer to the related links or feel free to contact us.*
