What is the energy of each photon

Reference no: EM13993007

Pulsed dye lasers emit light of wavelength 585 nmin 0.450 ms pulses to remove skin blemishes such as birthmarks. The beam is usually focused onto a circular spot 5.00 mm in diameter. Suppose that the output of one such laser is 20.0 W .

Part A. What is the energy of each photon, in (Ephantom=eV)

Part B. How many photons per square millimeter are delivered to the blemish during each pulse?eV (n=phantoms/mm^2)
