What is diffraction

Diffraction :

Diffraction is the bonding of light around an edge of the obstacle such as the edge of the slit we can diffraction of light through the crack between two fingers at the distant source.

Diffraction of any kind of waves depends upon the wavelength and the size of the obstacle. 

For significant diffraction, the ratio of λ/d should be 1. 

There are two types of diffraction :

  1. Fresnel diffraction
  2. Fraunhofer diffraction
