Question

Assertion (A): X-rays are emitted when there is transition of electrons in the inner orbits of an atom.

Reason (R): Gama radiations are given out from the nucleus.

Options

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

Explanation:

X-rays are produced when electrons make transitions in the inner orbits of an atom. Gamma radiations are emitted from the nucleus of a radioactive atom. Both statements are true, but they describe different sources of radiation, so Reason (R) does not explain Assertion (A).
