AIIMS 2017 Physics X-rays Assertion Reason Question
In the following questions, a statement of assertion is given followed by a corresponding statement of reason. Assertion: The phenomenon of X⁻ray production is basically inverse of photoelectric effect. Reason: X⁻rays are electromagnetic waves.
If both assertion and reason are true and reason is correct explanation of assertion.
If both assertion and reason are true and reason is not correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Option B is correct because while the assertion that the phenomenon of X-ray production is the inverse of the photoelectric effect is true, the reason provided is not a correct explanation for the assertion. X-rays are indeed electromagnetic waves, but their production involves processes such as Bremsstrahlung and characteristic radiation, which differ fundamentally from the photoelectric effect.
Option A is incorrect because, although both statements are true, the reason does not explain the assertion. Option C is incorrect since the assertion is true, but the reason is also true, making this option invalid. Option D is not applicable as both statements are true.
