Which of the following pairs correctly identifies linear polarization types?

• A. Vertical and Horizontal
• B. Circular and Elliptical
• C. Left-handed and Right-handed
• D. Upward and Downward

Answer: (A)

Linear polarization means the electric field oscillates in a single fixed plane as the wave travels. Vertical and horizontal describe two fixed, orthogonal planes of oscillation, which are the standard linear polarization states used in practice. Circular and elliptical refer to cases where the field rotates over time, tracing a circle or ellipse, not staying in one plane. Left-handed and right-handed describe the rotation direction for circular polarization, not a linear state. Upward and downward aren’t standard descriptors for polarization orientation. So the pair that correctly identifies linear polarization types is vertical and horizontal.
