Laser Emitting Photons Problem
A laser emits a light beam with a power of 5 mW. The wavelength of the light is 374 nm. How many photons per second does this laser emit? (3mW=3mJ/s)
Hint: Calculate the energy of a single photon
Power=5mW (light beam) based on conversion provided I know this is equal to 5mJ/s
wavelength=374nm -> convert to m: 1nm=1x10-9m, so 374x10-9m
