1. The problem statement, all variables and given/known data If blue and red light are used on a photoelectric cell and they both have the same intensity (Power per area). Choose the correct option from the following 2. Relevant equations E = nhf Intensity = power/area Quantum effeciency = 100% 3. The attempt at a solution if they have the same intensity as in same power per area then the number of photons reaching the cell differs. Red has more photons than blue light does. Thus red should have higher current. a to d from left to right. The correct answer was a, Was the question phrased wrong and they meant by intensity the number of photons reaching the plate per sec? Or did they neglect the small difference between the two currents?
