Question

Explain the difference between LHC and RHC polarisations.

Answer 1

The difference between Left hand circularly polarized and right hand circularly polarized are as follows,

LHC - left hand circularly polarized	RHC - Right hand circularly polarized
Its wave equation is given as,	Its wave equation is given as,
Left- Hand-Circular (LHC) follows a counterclockwise pattern in its polarisation.	Right-Hand-Circular (RHC) follows a clockwise pattern in its polarisation.
The LHC polarization wave can be thought to arise from the circular motion depicted by inverting the oscillation in the y-direction.	If so for the LHC polarization then the RHC wave can be thought to arise from the circular motion depicted by inverting the oscillation in the z-direction
At this time angular momentum vector points in the +y-directionits direction of motion, and the will have negative helicity.	At this time its angular momentum vector points in the z-direction,its direction of motion, and the wave will have positive helicity.
