Assertio Wavelength of charachteristic X...

Assertio Wavelength of charachteristic X-rays is given by
`(1)/(lambda)prop((1)/(n_(1)^(2))-(1)/(n_(2)^(2)))`
in trasnition from ` n_(2) to n_(1)` . In the abvoe relation proportionality constant is series dependent. For different series (K-series, L-series, etc. ) value of this constant will be different.
Reason For L-series value of this constant is less than the value for K-series

A

If both Assertion and Reason ar true and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are true but Reason is not correct explanation of Assertion

C

If Assertion is true by Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C

This proportionality constant `prop(Z-b)^(2)`
For K-series : b=1
For L-series : b=7.4
