AIIMS 2017 Physics X-rays Assertion Reason Question

Type: Assertion Reason-conceptual-Medium-Class 12

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.

A

If both assertion and reason are true and reason is correct explanation of assertion.

B

If both assertion and reason are true and reason is not correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Correct Answer

Option B

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.
