Freshnal difraction: both the point source and screen is relatively close to the obstacle then forms difraction pattern. this situation is described as near field diffraction or freshnal diffraction.

Fraunhoffer diffraction: IF the source, obstacle and screen are far enough away that all lines from source to the obstacle can conside parllal,this pnenomenon is called fraunhoffer diffraction.

We will use fraunhofffer diffrction is usually simpler to analyze.

the diffraction in which the source obstacle and the screen are of enough distance. in this diffraction the waves are considered parallel. this is known as fraunhoffer or field diffraction

fraun hoffer diffraction is known as a abstacle and source and the screen are the close ly placed..and it is also known as the near field differaction...

frehnal diffraction: it is known as the obsatacle and source and screen are to be far away to the each other and it is also known as the far field differacton....

in freshnel difraction source and obstacle and the screen are close to each other this is also called near fieald difraction in fraunhoffer diffraction source and obstacle and screen are far apart to each other this also called farfield diffraction

In optics, the Fraunhofer diffraction equation is used to model the diffraction of waves when the diffraction pattern is viewed at a long distance
