THE DIFFRACTION OF LIGHT IS A MAIN CONCEPT OF PHYSICS AND HENCE THE PHYSICS IS ALSO A MAIN CONCEPT OF SCIENCE AND PHYSICS IS HAVING A WIDE AREA FOR THE DIFFRACTION PART AND HENCE WE HAVE A DEBUT ON THIS PART OF PHYSICS THAT IS DIFFRACTION.THE MEANING OF THE DIFFRACTION IN THE DICTIONARY IS

“THE PHENOMENON OF BENDING OF LIGHT ACROSS THE SHARP CORNERS OF THE ENCROACHMENT OF THE OBSTACLE OF LIGHT WITHIN THE LIMIT OF THE GEOMETRICAL SHADOW OF AN OPAQUE OBSTACLE IS KNOWN AS DIFFRACTION”

GRIMALDI WAS THE FIRST SCIENTIST WHO MADE SCINTIFIC OBSERVATIONS ON DIFFRACTION IN 1665.

LATER THE PHENOMENON OF DIFFRACTION WAS STUDIED BY NEWTON AND HOOKE. THOMAS YOUNG WAS THE FIRST TO APPLY WAVE THEORY OF LIGHT TO EXPLAIN THE PHENOMENON OF DIFFRACTION.

AND HENCE THE TWO SCIENTISTS WHO GAVE PERFECT DEFINITION FOR THE DIFFRACTION ARE FRESNEL AND FRAUNHOFER.

WE WILL STUDY ABOUT FRESNEL AND FRAUNHOFER DIFFRACTION LATER BUT NOW WE WILL COME ACROSS THE DIFFRACTION PATTREN AND ITS ADVANTAGES.

THE DIFFRACTION PATTREN IS THE MAIN SOMETHING RESEMBLES WITH THE PATTREN OF INTERFERENCE AND HENCE THE PART OF DIFFRACTION ALSO PLAYS A GREAT ROLE IN THE HUMAN LIFE.

SHADOW IS THE MAIN CAUSE OF THE PROCESS OF DIFFRACTION AND HENCE WITHOUT DIFFRACTION THEREIS NO SHADOW.
