Thank you for your reply.
I don't understand how we can explain that with the help of geometrical optics, I am asking for a bit elaborate answer. As light can not actually bend but, in diffraction phenomenon, light seems to be apparently bending.
I gave the article a read, could not find what I...
I know light has wave particle duality, I understand these two points very well,
1. Light moves as a probability function, taking all the possible paths at once. The alternate paths cancel themselves out, resulting in a particle-like combined motion.
2. When relatively close to an edge, some...
