what purpose has wavelength got to do with the scattering of light?

Asked by reema saxena | 1st Jan, 2014, 03:20: PM

Expert Answer:

Scattering is possible only when the  wavelength of the wave is comparable to the size of the object.
 
Example:
In crystals the interatomic distance is of the order of few Angstrom.
The wavelength of X - rays is also of the order of few Angstroms ( 0.1 to 100 A).
Therefore only X - rays can be used to determine the crystal structure.
