The frequency of the characterstic X ray of `K_(alpha)` line of metal targent 'M' is `2500 cm^(-1)` and the graoh between `sqrt(v)` Vs 'z' is as follows, then atomic number of M is

A

49

B

50

C

51

D

25

Text Solution

Verified by Experts

The correct Answer is:
C
`sqrt(v)=a(Z-b) " " sqrt(v)=aZ-ab`
`aZ = sqrt(v)+ab rarr Z = (sqrt(v))/(a)+b " " therefore y=mx + c`
