i have this question where i need to calculate the number of photons per second striking a black body and i dont know how to find it. information you are given is that Power = 0.10mV, wavelength = 5.0 x 10^-7. You have to calculate the frequency of light and energy per photon of light - i have done these two, but i cant do the last part of the question which asks to calculate the number of photons per second striking the black body.
can anyone help me?
