Fireflies emit light of wavelengths from 510 nm to 670 nm. They are about 90% efficient at converting chemical energy into light (compared to about 10% for an incandescent lightbulb). Most living organisms, including fireflies, use adenosine triphosphate (ATP) as an energy molecule. |
Part A Estimate the number of ATP molecules a firefly would use at 0.57 eV per molecule to produce one photon of 591-nm wavelength if all the energy came from ATP. Express your answer as an integer. |
Answer is NOT n = 4
