Differences between Fresnel and Fraunhofer Diffractions
Fresnel Diffraction
|
Fraunhofer Diffraction
|
The
source and the screen are at finite distance from the diffracting aperture
|
The source and the screen are at
infinite distance from the diffracting aperture
|
Near field diffraction
|
Far field
diffraction
|
The
wave fronts are divergent and are either spherical and cylindrical
|
The wave fronts are planar which
is realized by using convex lenses
|
No
mirror or lenses are used for observation
|
Diffracted light is collected by
lens as in a telescope
|
Stokes Line and Anti-Stokes Line Definitions
A Stoke line is radiation of line spectra in fluorescence or Raman scattering with longer wavelength than the exciting radiation.
An anti-Stokes line is radiation of line spectra in fluorescence or Raman scattering with shorter wavelength than the exciting radiation.
