4 Φεβ 2024 · Diffraction of Light is when light waves bend around obstacles or spread out as they pass through narrow openings, creating patterns of light and shadow. The diffraction of light is used in laser technology, determining the crystal structure, medical imaging, etc.

In order to form an interference pattern, the incident light must satisfy two conditions: (i) The light sources must be coherent. This means that the plane waves from the sources must maintain a constant phase relation. For example, if two waves are completely out of phase with φ=π, this phase difference must not change with time.
Hyugens-Fresnel principle. If one perturbs a plane wavefront, the Huygens wavelets will no longer constructively interfere at all points in space. Adding the wavelets by physical optics explains why light can turn corners and create fringes around images of objects.
