thankyou to all. Got it. :)

Thanks all, but not convinced. Some want to use particle theory, some want to use wave theory. I thought wave theory was supposed to be demonstrated by this experiment. Never mind that taking single 'points' seems to imply particle theory. Can anyone actually answer the question I put, which...

yeh...but...(I have a few 'yeh, buts') I thought that Huygens Principle was supposed to prove the wave nature of light and not the particle nature. Also, I get the maths which shows how the slight difference in distance traveled by wave fronts to points either side of the midline, results in...

The standard explanation for diffraction patterns from a single slit employs Huygens Principle and the production of secondary wavelets to form a new 'front'. These fronts reinforce constructively and destructively to produce the pattern. But...if you consider an infinite number of points...
