Explanation:
Halfwave plate:
A halfwave plate is an optical device that can alter the polarization state of light passing through it. It introduces a phase difference of π (180 degrees) between the two orthogonal components of the input light, effectively converting linearly polarized light to linearly polarized light with a different orientation.
Linearly polarized light:
When light is linearly polarized, the electric field oscillates in a single plane. The direction of this plane of oscillation determines the polarization direction of the light.
Effect of halfwave plate:
When linearly polarized light passes through a halfwave plate, the phase difference introduced by the plate changes the orientation of the electric field. As a result, the emergent light remains linearly polarized, but its polarization direction is rotated by 90 degrees.
Outcome:
Therefore, the emergent light after passing through a halfwave plate is linearly polarized with a different orientation. It does not change the polarization state from linear to circular or elliptical. The emergent light is simply linearly polarized along a different axis.
Therefore, the correct answer is option 'C' - The emergent light is linearly polarized.
