Answer» Answer: Explanation: RECALL E=hcλ E=(6.626×10−34)(3.0×108)560×10−9 E=3.550×10−19J Each PHOTON carries 3.550×10−19J of energy. A 100W SOURCE MEANS that it outputs 100J of energy every second. number of photons emitted = total energy output in one second / energy carried per photon n=1003.550×10−19=2.8×1020 (2sf) |
