Dear Dipti,

It is depend on the symmetry of the LC cell - if it is cylindrically symmetry your answer will be yes. But, in other cases the change of Angular Momentum induces a rotation on the cell and one would expect to see a rotation.

Cheers,

Dear Karimi,

Thanks for this answer. In any birfringent system twisted by theta, introduces a rotation of 2theta to RCP/LCP. Whether it is true experimentally.

Nonconservation of angular momentum of photon takes place in which cases.

Bye
