Hello, I wonder if the photons of a candle or a lamp (on earth) is also propagated to infinity in space as photons stars or not? Are steppes by the atmosphere? Another question, how many photon emits my lamp or candle in my 1h 1mn or? Thank you Sylvain
Hello, all photons propagate potentially infinite but in reality they are absorbed by dust and gas they pass. If the medium traversed is opaque, the light does not pass and the photon can not continue his journey. Given the weak light of a candle, I'm not sure that the light can actually go to infinity or simply out of the atmosphere, maybe if the atmosphere is very pure and transparent .. . For your second question, it is necessary to calculate the luminous flux, I let you take care of your calculator and give us the result.
