A dye laser emits a pulse at 448 nm that contains 6.90 × 1015 photons. What is the energy content (in mJ) of this pulse?
Homework Answers
Energy of the pulse is given by E = Nhc/
where N is
number of photons, h is Planck's constant, wavelength and c is
velocity of light. Therefore E = (6.90*10^15*
6.625*10^-34*3*10^8)/448*10^-9. = 0.306*10^-2 = 3.06*10-3 J = 3.06
mJ

A laser pulse with wavelength 515 nm contains 4.40 mJ of energy. Question: How many photons are in the laser pulse? Can someone please walk me through the steps? I have tried to solve this multiple times, but the 2 answers I thought were for sure it are A: 2.21 x 10^22 photon B: 4.40 Joules X (1 photon/3.860x10^-19 Joules) They were both wrong.
