A) \[0.43\,eV\]
B) \[1.10\,eV\]
C) \[1.36\,eV\]
D) \[2.47\,eV\]
Correct Answer: B
Solution :
[b] Since \[E\propto \frac{1}{\lambda }\], so energy corresponding to 5000 \[\overset{\text{o}}{\mathop{\text{A}}}\,\] is \[E=2.46eV\] Now, \[hv-W=e{{V}_{s}}\] Or \[2.46eV-W=1.36eV\] \[W=(2.46-1.36)eV=1.1eV\]You need to login to perform this action.
