As we learned

 

 

Diffraction -

The phenomenon of bending of light around the corners of an obstacle of the size of the wavelength of light is called diffraction. 

  • The phenomenon resulting from the superposition of secondary wavelets originating from different parts of the same wavefront is defined as a diffraction of light.
  •  Diffraction is the characteristic of all types of waves.
  •  The wavelength of the wave is directly proportional to its degree of diffraction.   

                 Condition for Diffraction: 

  • The essential condition for diffraction to occur is that the wavelength of light should be comparable to that of the size of the obstacle.

 Therefore option-3 is the correct option.
