I've tried repeating Thomas Young's experiment on multiple occasions, but I can't seem to get the same results. What I did was lite a candle and hold a note card with two closely adjacent slits in it in front of the candle. From that experiment, two pencils of light that didn't intersect regardless were created on my wall. I then did an experiment in which I placed two candles in parallel near a wall and a book between them. The area where light from both candles intersected on the wall appeared to be uniformly brighter than the areas where they didn't intersect. The sunlight that beamed through my blinds had the same results. I would think that if interference fringes had formed, the area of overlapping would not have been greatly brighter to my eye than the non-overlapping areas. Why didn't I see interference fringes? And why didn't the light in my first experiment diffract then overlap?
