Let number of photon be N
Total energy = N* energy of 1 photon
= N *
h*c/lambda
4.4*10^-3 = N * 6.626 *10^-34
*3*10^8/(525*10^-9)
N=1.162 *10^16

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.
