Torque on a quarter-wave plate… Where is the force? Where is the moment arm?
Answers
If you shine circularly polarized light (carrying angular momentum) through a quarter-wave plate, the light will emerge as linearly polarized light (carrying no angular momentum) from the other side. In order for momentum to be conserved, the plate must experience a torque.
HEY SAKNA HERE
When circularly polarized light is passed through a quarter-wave plate, the plate experiences a torque. I understand this is true because angular momentum must be conserved, but I don't understand what is happening in the plate. From a classical perspective, how is the light interacting with the electrons in the plate in order to create the torque? I prefer a physical description over a mathematical one. Thanks.
