Scenario: Having very little physics background (high school), and having forgot most of it, sometimes I catch myself thinking about some weird stuff. Today's though was: given a stationary light source (eg. campfire flames), is it physically possible for another light source (flashlight) to shine through it (given a high intensity)? With any sort of measurement, is it possible to detect the photons of the flashlight on the other side of the campfire?
Obs: I tried searching around in my old class books and on google, but could only find how to start a fire with a flashlight, which is not very useful in answering the question.
Obs2: I have no idea if this is the right place to ask it, but thought it might work.
