Abstract
The present work reports the interpretation of circular fringes appearing on a screen at a suitable distance from a sample cell when coherent beam of light (He-Ne Laser, Ar<sup>+</sup> Laser) of suitable power is incident on it. The dynamic fringes are characteristics of liquids used in the experiment. In the present work we have shown that these fringes are originated from suspended particles in the liquid. We have also estimated the sizes of the particles. The characteristic of the fringes follows Maxwell-Boltzmann type of distribution.
Keywords
- Dynamic fringes
- diameter and speed of suspended particles
