What is Diffraction ? Diffraction of light is the bending of light waves around the edges of an obstacle or aperture that has a size comparable to the wavelength of light . This results in the light spreading out and producing patterns of light and dark bands. Imagine you’re at a water park, and there’s a big wall with a small gap in it. You notice that when waves hit the gap, they don’t just go straight through; they start to spread out in a semicircle on the other side. This spreading ... Diffraction of Light : Know the definition and types of diffraction , such as Fraunhofer & Fresnel diffraction and single slit diffraction 4.1: Prelude to Diffraction Due to Huygens’s principle, we can imagine a wave front as equivalent to infinitely many point sources of waves. Thus, a wave from a slit can behave not as one wave but as an infinite number of point sources. These waves can interfere with each other, resulting in an interference pattern without the presence of a second slit. This phenomenon is called diffraction . 4.2: Single-Slit Diffraction Diffraction can send a wave around the edges of an opening or other ... Diffraction Meaning: It is the process by which a stream of light or wave is spread out as a result of passing via a narrow area or across an edge, generally accompanied by interference between the waveform produced. Consider a train crossing the tunnel, inside the tunnel the rays of the headlight will remain converged; however, as the train comes out of the tunnel, the same light spreads around the area. This is the diffraction of light . Here, we have discussed the types of diffraction like ...
