In Fraunhofer diffraction, the source lies at the principal focus of a lens L 1 which renders the light parallel as it falls on the aperture A second lens L 2 focuses parallel diffracted beams on the observing screen F, situated in the principal focal plane of L 2 In Fresnel diffraction, no lenses intervene...

Aperture is the size of the opening in the lens Some lenses have fixed apertures, but most photographic lenses have variable apertures to control the amount of light entering the lens This aperture is regulated by a diaphragm made of overlapping blades that can be adjusted to vary the size of the opening through which light pass The size of the opening also has a...

And so, given the distance to the screen, the width of the slit, and the wavelength of the light, we can use the equation y = L l / a to calculate where the first diffraction minimum will occur in the single slit diffraction pattern And we have learned that this is the point where the waves from point sources in the slit all cancel in pairs that are out of phase...
