I have a few questions regarding the waves (optics) section:
- Why does single slit diffraction cause fringes to be made?, I understand why it is made for 2 slits and the waves and constructively and destructively interfering, but i dont understand why it happens with single slit?
- is single slit diffraction because of interference?
- there was a question in a book that asked: "What happens to the fringe pattern if one of the double slits it blocked completely?" The answer was that there is no fringe pattern, but after blocking 1 slit, why doesn't it just become single slit diffraction?
