DifficultPhotons of wavelength $\lambda$ emitted by a source of power $P$ are incident on a photocell. If the current produced in the cell is $I$,then the percentage of incident photons which produce current in the photocell is: (where $h$ is Planck's constant and $c$ is the speed of light in vacuum)
- A$\frac{100 e P c}{I h \lambda}$
- B$\frac{100 I h c}{e P \lambda}$
- C$\frac{100 I h \lambda}{e P c}$
- D$\frac{100 e P \lambda}{I h c}$
