Question

Consider a metal used to prodeced some charateristic X-ray are give by `E` and wavelength as represented by `lambda`. Then which of the following is true:
A. `E(K_(alpha)) gt E(K_(beta)) gt E(K_(gamma))`
B. `E(M_(alpha)) gt E(L_(alpha)) gt E(K_(alpha))`
C. `lambda(K_(alpha)) gt lambda(K_(beta)) gt lambda(K_(gamma))`
D. `lambda(M_(alpha)) gt lambda(L_(alpha)) gt lamda(K_(alpha))`

Answer 1

Correct Answer - C::D
`K_(alpha)`: transition from `2 rarr1`
Similarly for `K_(beta):3 rarr,K_(gamma):4 rarrL_(alpha):3rarrM_(alpha):4rarr3`
Now we can compare energy and `lambda`.
