A) \[N\propto L\] and \[E\propto L\]
B) \[N\propto L\]and \[E\propto \frac{1}{\lambda }\]
C) \[N\propto \lambda \] and \[E\propto L\]
D) \[N\propto \frac{1}{\lambda }\]and \[E\propto \frac{1}{L}\]
Correct Answer: B
Solution :
[b] Number of photons emitted is proportional to the intensity. Also \[\frac{hc}{\lambda }={{W}_{0}}+E\].
