Hello all,
Guys, I just pointed out that I actually lacking in somewhere in the understanding of the phenomenon of diffraction of light, of which I am aware from no less than 10 years.
Recently I revised Huygens wave theory of Light and studied in what ways Newton criticize it.
At one of the place I found this:
Newton wrote: 'If light consists of undulations in an elastic medium it should diverge in every direction from each new centre of disturbance, and so, like sound, bend round all obstacles and obliterate all shadow.'
Newton did not know that in fact light does do this, but the effects are exceedingly small due to the very short wavelength of light.
Now after this the thing that I am unable to comprehend is that, How does a small wavelength of light prevent it to enter into all region of geometrical shadow? How does the wavelength magnitude related with the size of the obstacle, in order that diffraction may occur?
Hope I stated my question clearly.
Any help will be highly appreciated.
Thanks a bunch. :)
Regards
