A stellar object is emitting radiation at 1750 nm. If the detector is capturing 1x10^7 photons per second?

Question

at this wavelength, what is the total energy of the photons detected in a period of one hour?

Answer 1

the energy is E=hc/wavelength, where h is planck's constant and c is the speed of light. This gives you the energy of a single photon at this wavelength (be sure to convert the wavelength to m to cancel out with c!)
Now you know how many photons you have per second, so multiply the energy in one photon (determined above) by the number of photons emitted per second.
Now take this number, which is the energy per second (or power...) and multiply by 3600 (3600s/1hour), this is your answer!

Answer 2

toal energy is 800x10^nm photons per gazillionbillion neutrons at a level of 50000 electrons. sticking with the assumption of emittence of 1750mn photons per 11000 electronoids at a scale of 1:10
