The `K_(alpha)andK_(beta)` lines of charateristic X-ray spectrum of molybdenum are `0.76 overset(@)A and 0.64overset(@)A`, respectively. The wavelength of `L_(alpha)` line is

A

`1.4overset(@)A`

B

`2.4overset(@)A`

C

`4.1overset(@)A`

D

`3.6overset(@)A`

Text Solution

Verified by Experts

The correct Answer is:
C
`E_(2)E_(1)=(12375)/(0.76)eV`
`E_(3)-E_(1)=(12375)/(0.76) eV`
`:. " " E_(3)-E_(2)=(12375)/(0.64)-(12375)/(0.76)`
or `" " lambda_(L_(alpha))=(12375)/(E_(3)-E_(2))=4.1Å`
