A) \[4\,\lambda \]
B) \[\frac{\,\lambda }{4}\]
C) \[3.08\,\lambda \]
D) \[0.26\,\lambda \]
Correct Answer: B
Solution :
From Moseley?s low, we have \[\frac{{{\upsilon }_{41}}}{{{\upsilon }_{21}}}={{\left( \frac{41-1}{21-1} \right)}^{2}}=4\]\[\therefore \]\[{{\lambda }_{21}}=\frac{{{\lambda }_{41}}}{4}=\frac{\lambda }{4}\] Hence, the correction option is [b].You need to login to perform this action.
