Assertion : The frequency of \( \mathrm{K}_{\alpha} \mathrm{X} \)-radiations is greater than \( \mathrm{K}_{\beta} \) for a given target.
\( P \)
Reason \( : \mathrm{K}_{\alpha} \) radiation is produced when an
W) electron from \( \mathrm{n}=2 \) jumps into the vacancy in \( \mathrm{n}=1 \) orbit, whereas in \( \mathrm{K}_{\beta} \) radiation the transition takes place from \( \mathrm{n}=3 \) to \( \mathrm{n}=2 \).
- (1) A
(2) B
(3) \( \mathrm{C} \)
(4) D
(A) Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
(B) Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
