1. The problem statement, all variables and given/known data A certain laser outputs pure blue light (photon energy 3.1 eV) with power 800 milliwatts (0.8 watts). How many photons per second does this laser emit? 2. Relevant equations 1 Ws = 6.24151e18 might need E = hv or E = (hc)/fequency where h is 6.6e-34 3. The attempt at a solution not sure if i did it write but i took the .8 multiplied by the 6.24e18 (this is converting Ws to eV) then i x this number by the 3.1 eV to get 1.5479e19 this should be eV/s. then i am lost. not sure if that is even right so any help would be great!!
