According to Huygens’s principle, light waves incident on two slits will spread out and exhibit an interference pattern in the region beyond (Figure 14.4.2a). The pattern is called a diffraction pattern. On the other hand, if no bending occurs and the light wave continue to travel in ...
The pattern is a little different for a larger gap (which is not a slit), and a double slit and a diffraction grating, all of which are discussed in other lessons. A circular aperture pattern is similar, but circular instead of containing bars. But why does a diffraction (or interference...

Now, according to Huygens’ principle, every point between the edges is a source of waves. While the interference pattern studied above is formed due to the interference of twodifferentwaves emanating from twodifferentslits, a diffraction pattern is formed due to the interference ofdifferentwaves em...
