A circuit employs a silicon solar cell to detect flashes of light lasting 0.25 ss. The smallest current the circuit can detect reliably is 0.37 μA . Assuming that all photons reaching the solar cell give their energy to a charge carrier, what is the minimum power of a flash of light of wavelength 560 nmnm that can be detected? Express your answer with the appropriate units.
