Explanation:
What is Diffraction of light?
The bending of light waves around the corners of an obstacle and spreading of light waves into geometrical shadow is called diffraction. Fraunhofer Diffraction and Fresnel Diffraction are two Types of Diffraction of Light. Bending of Light around the corners of Window is an example of Diffraction.
Diffraction effect depends upon the size of the obstacle. Diffraction of light takes place if the size of the obstacle is comparable to the wavelength of light. Light waves are very small in wavelength,i.e, from 4×10-7 m to 7 × 10 -7 m. If the size of opening or obstacle is near to this limit, only then we can observe the phenomenon of diffraction.
