Consider four lasers whose wavelengths of light are 300nm, 546nm, 632nm, 1024nm. To operate, each uses an identical 3.0 V battery. During operation, the current drawn from each battery is as follows: 2.4 mA (300nm), 1.5 mA (546nm), 1.4 mA (632nm), and 0.75 mA (1024nm). Rank these lasers by the number of photons per second emitted from most photons to least photons. You can assume that the laser is 100% efficient at converting electrical energy into photons of light.
