Identify the type of polarization represented by the electric field equation: E = E0 cos(kt - ωt) x̂ - E0 sin(kt - ωt) ŷ.
Understand the Problem
The question is providing an equation for an electric field and is asking to identify the type of polarization it represents from the given options.
Answer
Left circularly polarized.
The final answer is left circularly polarized light.
Answer for screen readers
The final answer is left circularly polarized light.
More Information
A left circularly polarized wave means the electric field vector rotates counterclockwise in a circular motion when looking in the direction of propagation.
Tips
A common mistake is to confuse left and right circular polarization. Remember that for left circular polarization, the electric field rotates counterclockwise when viewed from a point looking towards the source.
