A) \[10hcx\]
B) \[\frac{hc}{10x}\]
C) \[\frac{10}{hcx}\]
D) None of these
Correct Answer: C
Solution :
[c] \[E=\frac{nhc}{\lambda }=nhc\overline{v}\left( \because \,\overline{v}=\frac{1}{\lambda } \right)\] \[\therefore 10=nhc\overline{v}\,\] or \[n=\frac{10}{hc\overline{v}}=\frac{10}{hcx}\]You need to login to perform this action.
