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.
