In X-ray spectrum wavelength `lamda` of line `K_(alpha)` depends on atomic number Z as

A

`lambda propZ^(2)`

B

`lambdaprop(Z-1)^(2)`

C

`lambdaprop(1)/((Z-1))`

D

`lambdaprop(1)/((Z-1)^(2))`

Text Solution

Verified by Experts

The correct Answer is:
D

In X-ray spectrum wavelength `lambda` of `K_(alpha)` line is given by
`(1)/(lambda_(K_(alpha)))=(3)/(4)(Z-1)^(2)`
`:. " " lambda_(K_(alpha))prop(1)/((Z-1)^(2))`

When high energetic electron beam , (i.e., cathode rays) strike the heavier metal, then X-ray are produced. Spectrum of X-ray are classified into two categories: (i) continous spectrum, and (ii) characteristic depends only on the potential difference across the electrode. But wavelength of characteristic spectrum depends on the atomic number (z) . The production of characteristic X-ray is due to the
