Maharashtra State Board: Class 11
Definition: Diffraction of Light
The bending of light near the edge of an obstacle or slit and spreading into the region of geometrical shadow is called diffraction of light.
Maharashtra State Board: Class 11
Definition: Fresnel Diffraction
The type of diffraction that occurs when the source or screen is at a finite distance from the diffracting object and fringes are not sharp and well-defined is called Fresnel diffraction.
Maharashtra State Board: Class 11
Definition: Fraunhofer Diffraction
The type of diffraction that occurs when the source and the observation screen are far away (effectively at infinite distance) from the diffracting object and fringes are not sharp and well-defined is called Fraunhofer diffraction.
