Obtain a relation between the frequencies of `K_(oo) K_(beta)` and `L_(alpha)` line for a target metrial .

Text Solution

Verified by Experts

From the energy diagram as shown in the following figure , we know that

Frequency of `K_(alpha)`- line is
`f_(alpha) = (E_(L) - E_(K))/(h)`
Frequency of `K_(beta)`- line is
`f_(beta) = (E_(M) - E_(K))/(h)`
Frequency of `L_(alpha)`- line is
`f'_(alpha) = (E_(M) - E_(L))/(h)`
Since ` E_(M) - (E_(K) = (E_(M) - E_(L)) + (E_(L) - E_(K))`
`:.f_(beta) = f_(alpha) + f'_(a)`
