Answer:
Introduction:
When plane polarised light passes through a polaroid, it becomes linearly polarised in the direction perpendicular to the axis of the polaroid. If the polaroid is given a complete rotation about the direction of propagation, the optical properties of the polaroid change, and the observed effects vary depending on the angle of rotation.
Explanation:
1. Plane Polarised Light:
When plane polarised light is incident on a polaroid, the polaroid only allows the vibrations of light in one plane to pass through. The transmitted light becomes linearly polarised in the direction perpendicular to the axis of the polaroid.
2. Complete Rotation:
If the polaroid is given a complete rotation about the direction of propagation, the angle between the axis of the polaroid and the direction of polarisation of the light changes continuously. This rotation affects the intensity of the transmitted light.
3. Observations:
The observed effects depend on the angle of rotation of the polaroid. Let's discuss the options one by one:
A. The intensity of light gradually decreases to zero and then remains as zero:
This observation is incorrect because a complete rotation of the polaroid does not result in the complete extinction of light. The intensity of light passing through the polaroid will vary, but it will not become zero.
B. Intensity of light becomes maximum twice and zero twice:
This observation is also incorrect. A complete rotation of the polaroid does not cause the intensity of light to become zero twice. It only happens once when the axis of the polaroid is perpendicular to the direction of polarisation.
C. The intensity of light becomes maximum and stays maximum:
This observation is incorrect as well. The intensity of light passing through the polaroid will vary but it will not stay maximum throughout the rotation.
D. Intensity of light does not change:
This observation is the correct answer. When the polaroid is given a complete rotation, the intensity of light passing through it does not change. The polaroid only affects the polarization of light, not its intensity.
Conclusion:
When plane polarised light passes through a polaroid and the polaroid is given a complete rotation, the intensity of light does not change. This is the correct observation.
