So i was wondering...if you have 2 surfaces of different areas..one bigger and one smaller...and the one with a smaller area disperses light through a lens..does more light travel through the one with the lens or the other or does the same amount of light travel through both?
To get further details into this question and how I came to it. I was thinking if you have 2 cars, one with a big headlight that had no lenses in front of it and one with a lens but smaller headlight and the headlights get covered with the exact same amount of dust...(the same thickness on a square cm) will one car have brighter headlights or just the same?(of course you have the same exact light source in both of them)
