What does copenhagen interpretation say about a single slit?

Question

I would think that both the pilot wave theory (Bohm interpretation) and the Copenhagen interpretation would explain the two slit experiment, but what about when there is a single slit?

When there is a single slit, do photons act like a waves or particles? That is if it acts like a wave there should be a gradient in the center, and if it acts like a particle then it should be a projection of the slit.

I would think with 1 slit, the pilot wave theory would act like a particle, where as I would think Copenhagen interpretation would act like a wave although I must admit I don't know enough about copenhagen interpretation to know if that is correct.

Answer 1

You will get a bell curve. experimentally proven fact
One can interpret it as a wave.

Answer 2

looks good to me
