AIIMS 2019 Physics Polarization Assertion Reason Question
Assertion: Incoming light reflected by earth is partially polarized.
Reason: Atmospheric particle polarize the light
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
The assertion is true because direct sunlight is indeed unpolarized, and as it passes through the atmosphere, scattering occurs due to tiny particles, water (H₂O), and air molecules, which leads to a polarization pattern in the scattered light. The reason is also true as it accurately describes the scattering process that causes the polarization of light, making it the correct explanation of the assertion. Other options are incorrect because they either misrepresent the truth of the assertion or the reason, failing to recognize the relationship between the scattering phenomenon and the resulting polarization of sunlight.
