Double-slit time diffraction at optical frequencies Nature Physics

WebDiffraction is a general characteristic of all types of waves, be it sound wave, light wave, water wave etc. Diffraction is bending of waves around sharp edges into the geometrically shadowed region. WebDiffraction can be demonstrated by placing small barriers and obstacles in a ripple tank and observing the path of the water waves as they encounter the obstacles. The waves are seen to pass around the barrier into the regions behind it; subsequently the water behind the barrier is disturbed. small iris scissors
