Theta diffraction
WebAlso, let us learn what happens in a single slit diffraction experiment. We can observe single slit diffraction when light passes through a single slit whose width (w) is on the order of the wavelength of the light. The … WebRegardless of the huge improvements that have occurred for X-ray generation, the techniques used to measure the intensities and angles of diffraction patterns have evolved over time.In the first diffraction experiment, Friedrich and Knipping (1912) used a film sensitive to X-rays, but even in the same year, Bragg used an ionization chamber mounted …

Atmosphere consists of many different particles and molecules of gases and dirt, suspended or in relative motion. When sunlight passes through the atmosphere, it hits these particles and gets diffracted. This diffraction also scatters light.
