If the radiation of `Mo (Z = 42)` has a wevelength of `0.71Å`, calculate wevelength of the corresponding radiation of `Cu,i.e. , k_(alpha)for Cu (Z = 29) assuming b = 1`.

A

2.52 Å

B

1.52 Å

C

1.98 Å

D

3.22 Å

Text Solution

Verified by Experts

The correct Answer is:
B
According to Moseley's Law : `rArr (Z-1)^2 prop V`
or `(Z-1)^2 prop 1//lambda`
`=0.71xx(41/28)^2`=1.52 Å
