Understanding Rayleigh Scattering: Why do Atoms Scatter Light?

Click For Summary
SUMMARY

Rayleigh scattering occurs when atoms absorb light at specific frequencies and subsequently scatter it in various directions. This phenomenon is primarily due to the fundamental vibrations of atoms within molecules, which exchange energy with incident light, leading to scattering. Smaller atoms are known to scatter higher frequency light due to their size and the interaction with the electromagnetic fields of photons. Understanding these principles is essential for grasping the underlying mechanics of light scattering.

i am reading about Rayleigh scattering in light and have come to understand that atoms absorb light of particular frequencies and then scatter it in different directions.

But why do they scatter the light on the first place? Also, why do smaller atoms scatter higher frequency light?

Scattering of light: A molecule will scatter light. Reason: The fundamental vibrations of the atoms in molecule exchange energy with the incident light. Therefore scattering occurs. It can also be due to absorption/emission of light by atoms. But there could be several other reasons.
For your second question: I think you need to read some book. Just look into 'particle size relation or approximation' under Rayleigh scattering.
cheers.
 


Doesn't Rayleigh scattering have something to do with the molecule affecting the photons E and B fields altering its path . I hope some one else can elaborate on this more .
